Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31510664, here are decompositions:

7 + 31510657 = 31510664
37 + 31510627 = 31510664
61 + 31510603 = 31510664
103 + 31510561 = 31510664
277 + 31510387 = 31510664
421 + 31510243 = 31510664
571 + 31510093 = 31510664
643 + 31510021 = 31510664

Showing the first eight; more decompositions exist.
