Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467758, here are decompositions:

31 + 31467727 = 31467758
37 + 31467721 = 31467758
67 + 31467691 = 31467758
199 + 31467559 = 31467758
277 + 31467481 = 31467758
457 + 31467301 = 31467758
499 + 31467259 = 31467758
577 + 31467181 = 31467758

Showing the first eight; more decompositions exist.
