Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556076, here are decompositions:

43 + 31556033 = 31556076
107 + 31555969 = 31556076
109 + 31555967 = 31556076
127 + 31555949 = 31556076
137 + 31555939 = 31556076
199 + 31555877 = 31556076
263 + 31555813 = 31556076
313 + 31555763 = 31556076

Showing the first eight; more decompositions exist.
