Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31614810, here are decompositions:

13 + 31614797 = 31614810
23 + 31614787 = 31614810
41 + 31614769 = 31614810
103 + 31614707 = 31614810
107 + 31614703 = 31614810
109 + 31614701 = 31614810
113 + 31614697 = 31614810
163 + 31614647 = 31614810

Showing the first eight; more decompositions exist.
