Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480762, here are decompositions:

29 + 31480733 = 31480762
113 + 31480649 = 31480762
233 + 31480529 = 31480762
389 + 31480373 = 31480762
503 + 31480259 = 31480762
659 + 31480103 = 31480762
683 + 31480079 = 31480762
701 + 31480061 = 31480762

Showing the first eight; more decompositions exist.
