Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495074, here are decompositions:

11 + 31495063 = 31495074
31 + 31495043 = 31495074
71 + 31495003 = 31495074
131 + 31494943 = 31495074
137 + 31494937 = 31495074
151 + 31494923 = 31495074
167 + 31494907 = 31495074
257 + 31494817 = 31495074

Showing the first eight; more decompositions exist.
