Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495016, here are decompositions:

13 + 31495003 = 31495016
37 + 31494979 = 31495016
67 + 31494949 = 31495016
73 + 31494943 = 31495016
79 + 31494937 = 31495016
97 + 31494919 = 31495016
109 + 31494907 = 31495016
199 + 31494817 = 31495016

Showing the first eight; more decompositions exist.
