Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496066, here are decompositions:

313 + 31495753 = 31496066
337 + 31495729 = 31496066
373 + 31495693 = 31496066
409 + 31495657 = 31496066
463 + 31495603 = 31496066
619 + 31495447 = 31496066
643 + 31495423 = 31496066
709 + 31495357 = 31496066

Showing the first eight; more decompositions exist.
