Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480676, here are decompositions:

37 + 31480639 = 31480676
307 + 31480369 = 31480676
547 + 31480129 = 31480676
727 + 31479949 = 31480676
859 + 31479817 = 31480676
883 + 31479793 = 31480676
907 + 31479769 = 31480676
919 + 31479757 = 31480676

Showing the first eight; more decompositions exist.
