Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576798, here are decompositions:

47 + 31576751 = 31576798
59 + 31576739 = 31576798
89 + 31576709 = 31576798
179 + 31576619 = 31576798
257 + 31576541 = 31576798
269 + 31576529 = 31576798
359 + 31576439 = 31576798
389 + 31576409 = 31576798

Showing the first eight; more decompositions exist.
