Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556110, here are decompositions:

11 + 31556099 = 31556110
29 + 31556081 = 31556110
233 + 31555877 = 31556110
239 + 31555871 = 31556110
269 + 31555841 = 31556110
347 + 31555763 = 31556110
449 + 31555661 = 31556110
479 + 31555631 = 31556110

Showing the first eight; more decompositions exist.
