Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496786, here are decompositions:

3 + 31496783 = 31496786
7 + 31496779 = 31496786
67 + 31496719 = 31496786
109 + 31496677 = 31496786
193 + 31496593 = 31496786
199 + 31496587 = 31496786
337 + 31496449 = 31496786
367 + 31496419 = 31496786

Showing the first eight; more decompositions exist.
