Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1006656, here are decompositions:

5 + 1006651 = 1006656
19 + 1006637 = 1006656
23 + 1006633 = 1006656
43 + 1006613 = 1006656
47 + 1006609 = 1006656
67 + 1006589 = 1006656
73 + 1006583 = 1006656
97 + 1006559 = 1006656

Showing the first eight; more decompositions exist.
