Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607606, here are decompositions:

7 + 31607599 = 31607606
103 + 31607503 = 31607606
157 + 31607449 = 31607606
307 + 31607299 = 31607606
313 + 31607293 = 31607606
379 + 31607227 = 31607606
643 + 31606963 = 31607606
727 + 31606879 = 31607606

Showing the first eight; more decompositions exist.
