Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607562, here are decompositions:

11 + 31607551 = 31607562
31 + 31607531 = 31607562
59 + 31607503 = 31607562
73 + 31607489 = 31607562
89 + 31607473 = 31607562
101 + 31607461 = 31607562
113 + 31607449 = 31607562
139 + 31607423 = 31607562

Showing the first eight; more decompositions exist.
