Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607246, here are decompositions:

19 + 31607227 = 31607246
109 + 31607137 = 31607246
199 + 31607047 = 31607246
283 + 31606963 = 31607246
367 + 31606879 = 31607246
709 + 31606537 = 31607246
823 + 31606423 = 31607246
859 + 31606387 = 31607246

Showing the first eight; more decompositions exist.
