Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608056, here are decompositions:

19 + 31608037 = 31608056
43 + 31608013 = 31608056
199 + 31607857 = 31608056
367 + 31607689 = 31608056
373 + 31607683 = 31608056
457 + 31607599 = 31608056
607 + 31607449 = 31608056
757 + 31607299 = 31608056

Showing the first eight; more decompositions exist.
