Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042656, here are decompositions:

23 + 1042633 = 1042656
37 + 1042619 = 1042656
47 + 1042609 = 1042656
59 + 1042597 = 1042656
73 + 1042583 = 1042656
79 + 1042577 = 1042656
127 + 1042529 = 1042656
137 + 1042519 = 1042656

Showing the first eight; more decompositions exist.
