Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474732, here are decompositions:

11 + 31474721 = 31474732
41 + 31474691 = 31474732
59 + 31474673 = 31474732
131 + 31474601 = 31474732
173 + 31474559 = 31474732
251 + 31474481 = 31474732
389 + 31474343 = 31474732
431 + 31474301 = 31474732

Showing the first eight; more decompositions exist.
