Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31614660, here are decompositions:

13 + 31614647 = 31614660
17 + 31614643 = 31614660
19 + 31614641 = 31614660
29 + 31614631 = 31614660
59 + 31614601 = 31614660
73 + 31614587 = 31614660
97 + 31614563 = 31614660
101 + 31614559 = 31614660

Showing the first eight; more decompositions exist.
