Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567688, here are decompositions:

7 + 31567681 = 31567688
67 + 31567621 = 31567688
277 + 31567411 = 31567688
409 + 31567279 = 31567688
421 + 31567267 = 31567688
457 + 31567231 = 31567688
601 + 31567087 = 31567688
709 + 31566979 = 31567688

Showing the first eight; more decompositions exist.
