Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607310, here are decompositions:

11 + 31607299 = 31607310
13 + 31607297 = 31607310
17 + 31607293 = 31607310
19 + 31607291 = 31607310
29 + 31607281 = 31607310
47 + 31607263 = 31607310
73 + 31607237 = 31607310
83 + 31607227 = 31607310

Showing the first eight; more decompositions exist.
