Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467932, here are decompositions:

79 + 31467853 = 31467932
103 + 31467829 = 31467932
211 + 31467721 = 31467932
241 + 31467691 = 31467932
373 + 31467559 = 31467932
499 + 31467433 = 31467932
631 + 31467301 = 31467932
673 + 31467259 = 31467932

Showing the first eight; more decompositions exist.
