Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495226, here are decompositions:

13 + 31495213 = 31495226
73 + 31495153 = 31495226
79 + 31495147 = 31495226
109 + 31495117 = 31495226
163 + 31495063 = 31495226
223 + 31495003 = 31495226
277 + 31494949 = 31495226
283 + 31494943 = 31495226

Showing the first eight; more decompositions exist.
