Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495756, here are decompositions:

3 + 31495753 = 31495756
23 + 31495733 = 31495756
167 + 31495589 = 31495756
233 + 31495523 = 31495756
239 + 31495517 = 31495756
263 + 31495493 = 31495756
293 + 31495463 = 31495756
353 + 31495403 = 31495756

Showing the first eight; more decompositions exist.
