Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 964640, here are decompositions:

3 + 964637 = 964640
31 + 964609 = 964640
109 + 964531 = 964640
139 + 964501 = 964640
223 + 964417 = 964640
277 + 964363 = 964640
283 + 964357 = 964640
307 + 964333 = 964640

Showing the first eight; more decompositions exist.
