Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576792, here are decompositions:

41 + 31576751 = 31576792
53 + 31576739 = 31576792
83 + 31576709 = 31576792
89 + 31576703 = 31576792
173 + 31576619 = 31576792
251 + 31576541 = 31576792
263 + 31576529 = 31576792
281 + 31576511 = 31576792

Showing the first eight; more decompositions exist.
