Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31614828, here are decompositions:

31 + 31614797 = 31614828
41 + 31614787 = 31614828
59 + 31614769 = 31614828
127 + 31614701 = 31614828
131 + 31614697 = 31614828
151 + 31614677 = 31614828
181 + 31614647 = 31614828
197 + 31614631 = 31614828

Showing the first eight; more decompositions exist.
