Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495896, here are decompositions:

17 + 31495879 = 31495896
37 + 31495859 = 31495896
139 + 31495757 = 31495896
163 + 31495733 = 31495896
167 + 31495729 = 31495896
233 + 31495663 = 31495896
239 + 31495657 = 31495896
293 + 31495603 = 31495896

Showing the first eight; more decompositions exist.
