Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556104, here are decompositions:

5 + 31556099 = 31556104
23 + 31556081 = 31556104
71 + 31556033 = 31556104
113 + 31555991 = 31556104
137 + 31555967 = 31556104
197 + 31555907 = 31556104
227 + 31555877 = 31556104
233 + 31555871 = 31556104

Showing the first eight; more decompositions exist.
