Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495656, here are decompositions:

53 + 31495603 = 31495656
67 + 31495589 = 31495656
139 + 31495517 = 31495656
163 + 31495493 = 31495656
193 + 31495463 = 31495656
233 + 31495423 = 31495656
239 + 31495417 = 31495656
383 + 31495273 = 31495656

Showing the first eight; more decompositions exist.
