Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567712, here are decompositions:

3 + 31567709 = 31567712
13 + 31567699 = 31567712
19 + 31567693 = 31567712
31 + 31567681 = 31567712
109 + 31567603 = 31567712
199 + 31567513 = 31567712
283 + 31567429 = 31567712
433 + 31567279 = 31567712

Showing the first eight; more decompositions exist.
