Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 966816, here are decompositions:

13 + 966803 = 966816
89 + 966727 = 966816
139 + 966677 = 966816
157 + 966659 = 966816
163 + 966653 = 966816
197 + 966619 = 966816
199 + 966617 = 966816
233 + 966583 = 966816

Showing the first eight; more decompositions exist.
