Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480586, here are decompositions:

79 + 31480507 = 31480586
457 + 31480129 = 31480586
757 + 31479829 = 31480586
769 + 31479817 = 31480586
829 + 31479757 = 31480586
937 + 31479649 = 31480586
967 + 31479619 = 31480586
997 + 31479589 = 31480586

Showing the first eight; more decompositions exist.
