Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492288, here are decompositions:

11 + 31492277 = 31492288
29 + 31492259 = 31492288
131 + 31492157 = 31492288
197 + 31492091 = 31492288
227 + 31492061 = 31492288
257 + 31492031 = 31492288
701 + 31491587 = 31492288
761 + 31491527 = 31492288

Showing the first eight; more decompositions exist.
