Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655648, here are decompositions:

7 + 8655641 = 8655648
11 + 8655637 = 8655648
17 + 8655631 = 8655648
19 + 8655629 = 8655648
37 + 8655611 = 8655648
151 + 8655497 = 8655648
191 + 8655457 = 8655648
227 + 8655421 = 8655648

Showing the first eight; more decompositions exist.
