Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8608656, here are decompositions:

29 + 8608627 = 8608656
37 + 8608619 = 8608656
47 + 8608609 = 8608656
53 + 8608603 = 8608656
59 + 8608597 = 8608656
73 + 8608583 = 8608656
83 + 8608573 = 8608656
103 + 8608553 = 8608656

Showing the first eight; more decompositions exist.
