Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495796, here are decompositions:

43 + 31495753 = 31495796
67 + 31495729 = 31495796
103 + 31495693 = 31495796
139 + 31495657 = 31495796
193 + 31495603 = 31495796
349 + 31495447 = 31495796
373 + 31495423 = 31495796
379 + 31495417 = 31495796

Showing the first eight; more decompositions exist.
