Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31575074, here are decompositions:

163 + 31574911 = 31575074
211 + 31574863 = 31575074
373 + 31574701 = 31575074
397 + 31574677 = 31575074
577 + 31574497 = 31575074
607 + 31574467 = 31575074
631 + 31574443 = 31575074
967 + 31574107 = 31575074

Showing the first eight; more decompositions exist.
