Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556134, here are decompositions:

53 + 31556081 = 31556134
101 + 31556033 = 31556134
167 + 31555967 = 31556134
227 + 31555907 = 31556134
257 + 31555877 = 31556134
263 + 31555871 = 31556134
293 + 31555841 = 31556134
353 + 31555781 = 31556134

Showing the first eight; more decompositions exist.
