Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 943440, here are decompositions:

11 + 943429 = 943440
19 + 943421 = 943440
31 + 943409 = 943440
37 + 943403 = 943440
53 + 943387 = 943440
67 + 943373 = 943440
73 + 943367 = 943440
83 + 943357 = 943440

Showing the first eight; more decompositions exist.
