Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556276, here are decompositions:

127 + 31556149 = 31556276
163 + 31556113 = 31556276
277 + 31555999 = 31556276
307 + 31555969 = 31556276
337 + 31555939 = 31556276
463 + 31555813 = 31556276
613 + 31555663 = 31556276
643 + 31555633 = 31556276

Showing the first eight; more decompositions exist.
