Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556414, here are decompositions:

7 + 31556407 = 31556414
61 + 31556353 = 31556414
73 + 31556341 = 31556414
271 + 31556143 = 31556414
433 + 31555981 = 31556414
457 + 31555957 = 31556414
523 + 31555891 = 31556414
541 + 31555873 = 31556414

Showing the first eight; more decompositions exist.
