Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556092, here are decompositions:

11 + 31556081 = 31556092
59 + 31556033 = 31556092
101 + 31555991 = 31556092
251 + 31555841 = 31556092
311 + 31555781 = 31556092
353 + 31555739 = 31556092
431 + 31555661 = 31556092
461 + 31555631 = 31556092

Showing the first eight; more decompositions exist.
