Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556924, here are decompositions:

13 + 31556911 = 31556924
67 + 31556857 = 31556924
97 + 31556827 = 31556924
271 + 31556653 = 31556924
277 + 31556647 = 31556924
367 + 31556557 = 31556924
457 + 31556467 = 31556924
463 + 31556461 = 31556924

Showing the first eight; more decompositions exist.
