Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567736, here are decompositions:

7 + 31567729 = 31567736
19 + 31567717 = 31567736
37 + 31567699 = 31567736
43 + 31567693 = 31567736
223 + 31567513 = 31567736
307 + 31567429 = 31567736
367 + 31567369 = 31567736
439 + 31567297 = 31567736

Showing the first eight; more decompositions exist.
