Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467626, here are decompositions:

37 + 31467589 = 31467626
67 + 31467559 = 31467626
193 + 31467433 = 31467626
367 + 31467259 = 31467626
397 + 31467229 = 31467626
457 + 31467169 = 31467626
499 + 31467127 = 31467626
523 + 31467103 = 31467626

Showing the first eight; more decompositions exist.
