Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475068, here are decompositions:

59 + 31475009 = 31475068
71 + 31474997 = 31475068
137 + 31474931 = 31475068
239 + 31474829 = 31475068
347 + 31474721 = 31475068
467 + 31474601 = 31475068
491 + 31474577 = 31475068
509 + 31474559 = 31475068

Showing the first eight; more decompositions exist.
