Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516710, here are decompositions:

7 + 31516703 = 31516710
11 + 31516699 = 31516710
13 + 31516697 = 31516710
41 + 31516669 = 31516710
79 + 31516631 = 31516710
83 + 31516627 = 31516710
97 + 31516613 = 31516710
107 + 31516603 = 31516710

Showing the first eight; more decompositions exist.
