Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556652, here are decompositions:

5 + 31556647 = 31556652
13 + 31556639 = 31556652
151 + 31556501 = 31556652
163 + 31556489 = 31556652
173 + 31556479 = 31556652
191 + 31556461 = 31556652
229 + 31556423 = 31556652
263 + 31556389 = 31556652

Showing the first eight; more decompositions exist.
