Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467656, here are decompositions:

67 + 31467589 = 31467656
97 + 31467559 = 31467656
223 + 31467433 = 31467656
397 + 31467259 = 31467656
457 + 31467199 = 31467656
487 + 31467169 = 31467656
499 + 31467157 = 31467656
523 + 31467133 = 31467656

Showing the first eight; more decompositions exist.
