Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496666, here are decompositions:

67 + 31496599 = 31496666
73 + 31496593 = 31496666
79 + 31496587 = 31496666
127 + 31496539 = 31496666
277 + 31496389 = 31496666
337 + 31496329 = 31496666
349 + 31496317 = 31496666
373 + 31496293 = 31496666

Showing the first eight; more decompositions exist.
