Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1044540, here are decompositions:

11 + 1044529 = 1044540
23 + 1044517 = 1044540
31 + 1044509 = 1044540
61 + 1044479 = 1044540
83 + 1044457 = 1044540
89 + 1044451 = 1044540
97 + 1044443 = 1044540
103 + 1044437 = 1044540

Showing the first eight; more decompositions exist.
