Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516074, here are decompositions:

13 + 31516061 = 31516074
47 + 31516027 = 31516074
53 + 31516021 = 31516074
67 + 31516007 = 31516074
137 + 31515937 = 31516074
181 + 31515893 = 31516074
193 + 31515881 = 31516074
307 + 31515767 = 31516074

Showing the first eight; more decompositions exist.
