Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475062, here are decompositions:

53 + 31475009 = 31475062
131 + 31474931 = 31475062
233 + 31474829 = 31475062
389 + 31474673 = 31475062
461 + 31474601 = 31475062
491 + 31474571 = 31475062
503 + 31474559 = 31475062
659 + 31474403 = 31475062

Showing the first eight; more decompositions exist.
