Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556862, here are decompositions:

5 + 31556857 = 31556862
59 + 31556803 = 31556862
83 + 31556779 = 31556862
223 + 31556639 = 31556862
373 + 31556489 = 31556862
383 + 31556479 = 31556862
401 + 31556461 = 31556862
439 + 31556423 = 31556862

Showing the first eight; more decompositions exist.
