Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496006, here are decompositions:

109 + 31495897 = 31496006
127 + 31495879 = 31496006
277 + 31495729 = 31496006
313 + 31495693 = 31496006
349 + 31495657 = 31496006
673 + 31495333 = 31496006
733 + 31495273 = 31496006
853 + 31495153 = 31496006

Showing the first eight; more decompositions exist.
