Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31614690, here are decompositions:

13 + 31614677 = 31614690
43 + 31614647 = 31614690
47 + 31614643 = 31614690
59 + 31614631 = 31614690
89 + 31614601 = 31614690
103 + 31614587 = 31614690
127 + 31614563 = 31614690
131 + 31614559 = 31614690

Showing the first eight; more decompositions exist.
