Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607312, here are decompositions:

3 + 31607309 = 31607312
13 + 31607299 = 31607312
19 + 31607293 = 31607312
31 + 31607281 = 31607312
211 + 31607101 = 31607312
349 + 31606963 = 31607312
409 + 31606903 = 31607312
433 + 31606879 = 31607312

Showing the first eight; more decompositions exist.
