Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 966812, here are decompositions:

31 + 966781 = 966812
61 + 966751 = 966812
151 + 966661 = 966812
181 + 966631 = 966812
193 + 966619 = 966812
199 + 966613 = 966812
229 + 966583 = 966812
313 + 966499 = 966812

Showing the first eight; more decompositions exist.
