Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495056, here are decompositions:

13 + 31495043 = 31495056
37 + 31495019 = 31495056
53 + 31495003 = 31495056
107 + 31494949 = 31495056
113 + 31494943 = 31495056
137 + 31494919 = 31495056
149 + 31494907 = 31495056
239 + 31494817 = 31495056

Showing the first eight; more decompositions exist.
