Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607340, here are decompositions:

13 + 31607327 = 31607340
31 + 31607309 = 31607340
41 + 31607299 = 31607340
43 + 31607297 = 31607340
47 + 31607293 = 31607340
59 + 31607281 = 31607340
103 + 31607237 = 31607340
113 + 31607227 = 31607340

Showing the first eight; more decompositions exist.
