Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 940666, here are decompositions:

17 + 940649 = 940666
47 + 940619 = 940666
59 + 940607 = 940666
113 + 940553 = 940666
137 + 940529 = 940666
197 + 940469 = 940666
263 + 940403 = 940666
317 + 940349 = 940666

Showing the first eight; more decompositions exist.
