Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627718, here are decompositions:

79 + 31627639 = 31627718
151 + 31627567 = 31627718
181 + 31627537 = 31627718
307 + 31627411 = 31627718
457 + 31627261 = 31627718
691 + 31627027 = 31627718
739 + 31626979 = 31627718
751 + 31626967 = 31627718

Showing the first eight; more decompositions exist.
