Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31518296, here are decompositions:

37 + 31518259 = 31518296
67 + 31518229 = 31518296
157 + 31518139 = 31518296
409 + 31517887 = 31518296
547 + 31517749 = 31518296
643 + 31517653 = 31518296
709 + 31517587 = 31518296
739 + 31517557 = 31518296

Showing the first eight; more decompositions exist.
