Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556502, here are decompositions:

13 + 31556489 = 31556502
23 + 31556479 = 31556502
41 + 31556461 = 31556502
79 + 31556423 = 31556502
113 + 31556389 = 31556502
149 + 31556353 = 31556502
179 + 31556323 = 31556502
193 + 31556309 = 31556502

Showing the first eight; more decompositions exist.
