Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495964, here are decompositions:

43 + 31495921 = 31495964
67 + 31495897 = 31495964
163 + 31495801 = 31495964
211 + 31495753 = 31495964
223 + 31495741 = 31495964
271 + 31495693 = 31495964
307 + 31495657 = 31495964
373 + 31495591 = 31495964

Showing the first eight; more decompositions exist.
