Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607564, here are decompositions:

13 + 31607551 = 31607564
61 + 31607503 = 31607564
103 + 31607461 = 31607564
223 + 31607341 = 31607564
271 + 31607293 = 31607564
283 + 31607281 = 31607564
337 + 31607227 = 31607564
463 + 31607101 = 31607564

Showing the first eight; more decompositions exist.
