Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607512, here are decompositions:

23 + 31607489 = 31607512
89 + 31607423 = 31607512
113 + 31607399 = 31607512
149 + 31607363 = 31607512
311 + 31607201 = 31607512
359 + 31607153 = 31607512
569 + 31606943 = 31607512
593 + 31606919 = 31607512

Showing the first eight; more decompositions exist.
