Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467716, here are decompositions:

127 + 31467589 = 31467716
157 + 31467559 = 31467716
283 + 31467433 = 31467716
349 + 31467367 = 31467716
457 + 31467259 = 31467716
487 + 31467229 = 31467716
547 + 31467169 = 31467716
613 + 31467103 = 31467716

Showing the first eight; more decompositions exist.
