Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495314, here are decompositions:

41 + 31495273 = 31495314
73 + 31495241 = 31495314
101 + 31495213 = 31495314
127 + 31495187 = 31495314
157 + 31495157 = 31495314
167 + 31495147 = 31495314
197 + 31495117 = 31495314
251 + 31495063 = 31495314

Showing the first eight; more decompositions exist.
