Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492322, here are decompositions:

3 + 31492319 = 31492322
61 + 31492261 = 31492322
79 + 31492243 = 31492322
109 + 31492213 = 31492322
229 + 31492093 = 31492322
241 + 31492081 = 31492322
271 + 31492051 = 31492322
409 + 31491913 = 31492322

Showing the first eight; more decompositions exist.
