Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 966400, here are decompositions:

11 + 966389 = 966400
23 + 966377 = 966400
47 + 966353 = 966400
53 + 966347 = 966400
107 + 966293 = 966400
167 + 966233 = 966400
173 + 966227 = 966400
179 + 966221 = 966400

Showing the first eight; more decompositions exist.
