Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480544, here are decompositions:

37 + 31480507 = 31480544
103 + 31480441 = 31480544
163 + 31480381 = 31480544
523 + 31480021 = 31480544
727 + 31479817 = 31480544
751 + 31479793 = 31480544
787 + 31479757 = 31480544
967 + 31479577 = 31480544

Showing the first eight; more decompositions exist.
