Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495116, here are decompositions:

7 + 31495109 = 31495116
53 + 31495063 = 31495116
73 + 31495043 = 31495116
97 + 31495019 = 31495116
113 + 31495003 = 31495116
137 + 31494979 = 31495116
167 + 31494949 = 31495116
173 + 31494943 = 31495116

Showing the first eight; more decompositions exist.
