Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496636, here are decompositions:

37 + 31496599 = 31496636
43 + 31496593 = 31496636
97 + 31496539 = 31496636
307 + 31496329 = 31496636
373 + 31496263 = 31496636
463 + 31496173 = 31496636
739 + 31495897 = 31496636
757 + 31495879 = 31496636

Showing the first eight; more decompositions exist.
