Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627762, here are decompositions:

11 + 31627751 = 31627762
41 + 31627721 = 31627762
113 + 31627649 = 31627762
251 + 31627511 = 31627762
389 + 31627373 = 31627762
443 + 31627319 = 31627762
641 + 31627121 = 31627762
863 + 31626899 = 31627762

Showing the first eight; more decompositions exist.
