Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607756, here are decompositions:

67 + 31607689 = 31607756
73 + 31607683 = 31607756
127 + 31607629 = 31607756
157 + 31607599 = 31607756
283 + 31607473 = 31607756
307 + 31607449 = 31607756
457 + 31607299 = 31607756
463 + 31607293 = 31607756

Showing the first eight; more decompositions exist.
