Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516698, here are decompositions:

29 + 31516669 = 31516698
67 + 31516631 = 31516698
71 + 31516627 = 31516698
79 + 31516619 = 31516698
127 + 31516571 = 31516698
131 + 31516567 = 31516698
139 + 31516559 = 31516698
179 + 31516519 = 31516698

Showing the first eight; more decompositions exist.
