Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495696, here are decompositions:

3 + 31495693 = 31495696
5 + 31495691 = 31495696
107 + 31495589 = 31495696
173 + 31495523 = 31495696
179 + 31495517 = 31495696
227 + 31495469 = 31495696
233 + 31495463 = 31495696
293 + 31495403 = 31495696

Showing the first eight; more decompositions exist.
