Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607636, here are decompositions:

7 + 31607629 = 31607636
37 + 31607599 = 31607636
163 + 31607473 = 31607636
337 + 31607299 = 31607636
373 + 31607263 = 31607636
409 + 31607227 = 31607636
499 + 31607137 = 31607636
673 + 31606963 = 31607636

Showing the first eight; more decompositions exist.
