Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495014, here are decompositions:

11 + 31495003 = 31495014
71 + 31494943 = 31495014
107 + 31494907 = 31495014
127 + 31494887 = 31495014
197 + 31494817 = 31495014
233 + 31494781 = 31495014
251 + 31494763 = 31495014
277 + 31494737 = 31495014

Showing the first eight; more decompositions exist.
