Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475996, here are decompositions:

43 + 31475953 = 31475996
67 + 31475929 = 31475996
199 + 31475797 = 31475996
283 + 31475713 = 31475996
313 + 31475683 = 31475996
373 + 31475623 = 31475996
397 + 31475599 = 31475996
709 + 31475287 = 31475996

Showing the first eight; more decompositions exist.
