Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31518056, here are decompositions:

7 + 31518049 = 31518056
19 + 31518037 = 31518056
103 + 31517953 = 31518056
307 + 31517749 = 31518056
439 + 31517617 = 31518056
499 + 31517557 = 31518056
523 + 31517533 = 31518056
643 + 31517413 = 31518056

Showing the first eight; more decompositions exist.
