Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 966440, here are decompositions:

31 + 966409 = 966440
61 + 966379 = 966440
67 + 966373 = 966440
103 + 966337 = 966440
127 + 966313 = 966440
199 + 966241 = 966440
229 + 966211 = 966440
283 + 966157 = 966440

Showing the first eight; more decompositions exist.
