Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607328, here are decompositions:

19 + 31607309 = 31607328
29 + 31607299 = 31607328
31 + 31607297 = 31607328
37 + 31607291 = 31607328
47 + 31607281 = 31607328
101 + 31607227 = 31607328
127 + 31607201 = 31607328
191 + 31607137 = 31607328

Showing the first eight; more decompositions exist.
