Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465716, here are decompositions:

5 + 31465711 = 31465716
19 + 31465697 = 31465716
43 + 31465673 = 31465716
53 + 31465663 = 31465716
67 + 31465649 = 31465716
97 + 31465619 = 31465716
137 + 31465579 = 31465716
257 + 31465459 = 31465716

Showing the first eight; more decompositions exist.
