Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556064, here are decompositions:

31 + 31556033 = 31556064
53 + 31556011 = 31556064
73 + 31555991 = 31556064
83 + 31555981 = 31556064
97 + 31555967 = 31556064
107 + 31555957 = 31556064
131 + 31555933 = 31556064
157 + 31555907 = 31556064

Showing the first eight; more decompositions exist.
