Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495716, here are decompositions:

23 + 31495693 = 31495716
53 + 31495663 = 31495716
59 + 31495657 = 31495716
113 + 31495603 = 31495716
127 + 31495589 = 31495716
193 + 31495523 = 31495716
199 + 31495517 = 31495716
223 + 31495493 = 31495716

Showing the first eight; more decompositions exist.
