Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1024656, here are decompositions:

23 + 1024633 = 1024656
47 + 1024609 = 1024656
67 + 1024589 = 1024656
79 + 1024577 = 1024656
97 + 1024559 = 1024656
109 + 1024547 = 1024656
179 + 1024477 = 1024656
223 + 1024433 = 1024656

Showing the first eight; more decompositions exist.
