Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495934, here are decompositions:

13 + 31495921 = 31495934
37 + 31495897 = 31495934
181 + 31495753 = 31495934
193 + 31495741 = 31495934
241 + 31495693 = 31495934
271 + 31495663 = 31495934
277 + 31495657 = 31495934
331 + 31495603 = 31495934

Showing the first eight; more decompositions exist.
