Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 943640, here are decompositions:

3 + 943637 = 943640
37 + 943603 = 943640
73 + 943567 = 943640
97 + 943543 = 943640
163 + 943477 = 943640
211 + 943429 = 943640
277 + 943363 = 943640
283 + 943357 = 943640

Showing the first eight; more decompositions exist.
