Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 966642, here are decompositions:

11 + 966631 = 966642
23 + 966619 = 966642
29 + 966613 = 966642
59 + 966583 = 966642
151 + 966491 = 966642
179 + 966463 = 966642
211 + 966431 = 966642
223 + 966419 = 966642

Showing the first eight; more decompositions exist.
