Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495214, here are decompositions:

43 + 31495171 = 31495214
61 + 31495153 = 31495214
67 + 31495147 = 31495214
97 + 31495117 = 31495214
151 + 31495063 = 31495214
211 + 31495003 = 31495214
271 + 31494943 = 31495214
277 + 31494937 = 31495214

Showing the first eight; more decompositions exist.
