Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607316, here are decompositions:

7 + 31607309 = 31607316
17 + 31607299 = 31607316
19 + 31607297 = 31607316
23 + 31607293 = 31607316
53 + 31607263 = 31607316
79 + 31607237 = 31607316
89 + 31607227 = 31607316
109 + 31607207 = 31607316

Showing the first eight; more decompositions exist.
