Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607462, here are decompositions:

13 + 31607449 = 31607462
163 + 31607299 = 31607462
181 + 31607281 = 31607462
199 + 31607263 = 31607462
499 + 31606963 = 31607462
709 + 31606753 = 31607462
751 + 31606711 = 31607462
811 + 31606651 = 31607462

Showing the first eight; more decompositions exist.
