Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556964, here are decompositions:

7 + 31556957 = 31556964
41 + 31556923 = 31556964
53 + 31556911 = 31556964
107 + 31556857 = 31556964
137 + 31556827 = 31556964
151 + 31556813 = 31556964
193 + 31556771 = 31556964
223 + 31556741 = 31556964

Showing the first eight; more decompositions exist.
