Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495110, here are decompositions:

47 + 31495063 = 31495110
67 + 31495043 = 31495110
107 + 31495003 = 31495110
131 + 31494979 = 31495110
167 + 31494943 = 31495110
173 + 31494937 = 31495110
191 + 31494919 = 31495110
223 + 31494887 = 31495110

Showing the first eight; more decompositions exist.
