Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474758, here are decompositions:

11 + 31474747 = 31474758
37 + 31474721 = 31474758
67 + 31474691 = 31474758
71 + 31474687 = 31474758
89 + 31474669 = 31474758
157 + 31474601 = 31474758
181 + 31474577 = 31474758
199 + 31474559 = 31474758

Showing the first eight; more decompositions exist.
