Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495364, here are decompositions:

3 + 31495361 = 31495364
7 + 31495357 = 31495364
13 + 31495351 = 31495364
31 + 31495333 = 31495364
151 + 31495213 = 31495364
193 + 31495171 = 31495364
211 + 31495153 = 31495364
421 + 31494943 = 31495364

Showing the first eight; more decompositions exist.
