Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556612, here are decompositions:

151 + 31556461 = 31556612
223 + 31556389 = 31556612
271 + 31556341 = 31556612
463 + 31556149 = 31556612
499 + 31556113 = 31556612
601 + 31556011 = 31556612
613 + 31555999 = 31556612
631 + 31555981 = 31556612

Showing the first eight; more decompositions exist.
