Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1032638, here are decompositions:

31 + 1032607 = 1032638
37 + 1032601 = 1032638
67 + 1032571 = 1032638
97 + 1032541 = 1032638
127 + 1032511 = 1032638
181 + 1032457 = 1032638
241 + 1032397 = 1032638
331 + 1032307 = 1032638

Showing the first eight; more decompositions exist.
