Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607514, here are decompositions:

11 + 31607503 = 31607514
41 + 31607473 = 31607514
53 + 31607461 = 31607514
67 + 31607447 = 31607514
151 + 31607363 = 31607514
157 + 31607357 = 31607514
173 + 31607341 = 31607514
223 + 31607291 = 31607514

Showing the first eight; more decompositions exist.
