Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556712, here are decompositions:

59 + 31556653 = 31556712
73 + 31556639 = 31556712
211 + 31556501 = 31556712
223 + 31556489 = 31556712
233 + 31556479 = 31556712
251 + 31556461 = 31556712
331 + 31556381 = 31556712
359 + 31556353 = 31556712

Showing the first eight; more decompositions exist.
