Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8605656, here are decompositions:

19 + 8605637 = 8605656
47 + 8605609 = 8605656
79 + 8605577 = 8605656
89 + 8605567 = 8605656
113 + 8605543 = 8605656
127 + 8605529 = 8605656
193 + 8605463 = 8605656
223 + 8605433 = 8605656

Showing the first eight; more decompositions exist.
