Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607750, here are decompositions:

3 + 31607747 = 31607750
61 + 31607689 = 31607750
67 + 31607683 = 31607750
79 + 31607671 = 31607750
151 + 31607599 = 31607750
199 + 31607551 = 31607750
277 + 31607473 = 31607750
409 + 31607341 = 31607750

Showing the first eight; more decompositions exist.
