Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495224, here are decompositions:

11 + 31495213 = 31495224
37 + 31495187 = 31495224
53 + 31495171 = 31495224
67 + 31495157 = 31495224
71 + 31495153 = 31495224
107 + 31495117 = 31495224
181 + 31495043 = 31495224
281 + 31494943 = 31495224

Showing the first eight; more decompositions exist.
