Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516634, here are decompositions:

3 + 31516631 = 31516634
7 + 31516627 = 31516634
31 + 31516603 = 31516634
67 + 31516567 = 31516634
151 + 31516483 = 31516634
211 + 31516423 = 31516634
223 + 31516411 = 31516634
277 + 31516357 = 31516634

Showing the first eight; more decompositions exist.
