Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516766, here are decompositions:

13 + 31516753 = 31516766
37 + 31516729 = 31516766
67 + 31516699 = 31516766
97 + 31516669 = 31516766
139 + 31516627 = 31516766
163 + 31516603 = 31516766
199 + 31516567 = 31516766
223 + 31516543 = 31516766

Showing the first eight; more decompositions exist.
