Not as many as one would expect. And I don't know
any good way to search for them. 

Apart from the ones already mentioned, here are a few: 

EPSG:3572   "WGS 84 / North Pole LAEA Alaska"	Northern hemisphere - north of 45°N, including Arctic. 
EPSG:3574   "WGS 84 / North Pole LAEA Atlantic"	Northern hemisphere - north of 45°N, including Arctic.   
EPSG:3571   "WGS 84 / North Pole LAEA Bering Sea"	Northern hemisphere - north of 45°N, including Arctic.   
EPSG:3573   "WGS 84 / North Pole LAEA Canada"	Northern hemisphere - north of 45°N, including Arctic.   
EPSG:3575   "WGS 84 / North Pole LAEA Europe"	Northern hemisphere - north of 45°N, including Arctic.
EPSG:3576   "WGS 84 / North Pole LAEA Russia"	Northern hemisphere - north of 45°N, including Arctic.
EPSG:3832   "WGS 84 / PDC Mercator"		Pacific Ocean
EPSG:3973   "WGS 84 / NSIDC EASE-Grid North"	World - north of 0°N
EPSG:3974   "WGS 84 / NSIDC EASE-Grid South"	World - south of 0°N
EPSG:3975   "WGS 84 / NSIDC EASE-Grid Global"	World - 86°S to 86°N
EPSG:5041   "WGS 84 / UPS North (E,N)"		Northern hemisphere - north of 60°N onshore and offshore, including Arctic.
EPSG:5042   "WGS 84 / UPS South (E,N)"		Southern hemisphere - south of 60°S onshore and offshore - Antarctica.

If you can use ESRI codes as well, there are more to 
choose from (some of these may exist in EPSG, too):

ESRI:102001   "Canada_Albers_Equal_Area_Conic"
ESRI:102002   "Canada_Lambert_Conformal_Conic"
ESRI:102003   "USA_Contiguous_Albers_Equal_Area_Conic"
ESRI:102004   "USA_Contiguous_Lambert_Conformal_Conic"
ESRI:102005   "USA_Contiguous_Equidistant_Conic"
ESRI:102008   "North_America_Albers_Equal_Area_Conic"
ESRI:102009   "North_America_Lambert_Conformal_Conic"
ESRI:102010   "North_America_Equidistant_Conic"
ESRI:102011   "Africa_Sinusoidal"
ESRI:102012   "Asia_Lambert_Conformal_Conic"
ESRI:102013   "Europe_Albers_Equal_Area_Conic"
ESRI:102014   "Europe_Lambert_Conformal_Conic"
ESRI:102015   "South_America_Lambert_Conformal_Conic"
ESRI:102016   "North_Pole_Azimuthal_Equidistant"
ESRI:102017   "North_Pole_Lambert_Azimuthal_Equal_Area"
ESRI:102018   "North_Pole_Stereographic"
ESRI:102019   "South_Pole_Azimuthal_Equidistant"
ESRI:102020   "South_Pole_Lambert_Azimuthal_Equal_Area"
ESRI:102021   "South_Pole_Stereographic"
ESRI:102022   "Africa_Albers_Equal_Area_Conic"
ESRI:102023   "Africa_Equidistant_Conic"
ESRI:102024   "Africa_Lambert_Conformal_Conic"
ESRI:102025   "Asia_North_Albers_Equal_Area_Conic"
ESRI:102026   "Asia_North_Equidistant_Conic"
ESRI:102027   "Asia_North_Lambert_Conformal_Conic"
ESRI:102028   "Asia_South_Albers_Equal_Area_Conic"
ESRI:102029   "Asia_South_Equidistant_Conic"
ESRI:102030   "Asia_South_Lambert_Conformal_Conic"
ESRI:102031   "Europe_Equidistant_Conic"
ESRI:102032   "South_America_Equidistant_Conic"
ESRI:102033   "South_America_Albers_Equal_Area_Conic"
ESRI:102034   "North_Pole_Gnomonic"
ESRI:102035   "North_Pole_Orthographic"
ESRI:102036   "South_Pole_Gnomonic"
ESRI:102037   "South_Pole_Orthographic"

You can find the definitions at http://help.arcgis.com/en/arcims/10.0/mainhelp/mergedProjects/ArcXMLGuide/elements/pcs.htm
(And the ESRI codes 53001 to 54053 give various world maps.)

A map projection for Russia can be found here http://nsidc.org/data/docs/fgdc/ggd601_russia_soil_maps/index.html
I don't know if it has any official status. If it is important to keep north up,
one would instead use some Mercator with central meridian in the middle of Russia.
