Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655864, here are decompositions:

5 + 8655859 = 8655864
23 + 8655841 = 8655864
103 + 8655761 = 8655864
131 + 8655733 = 8655864
157 + 8655707 = 8655864
163 + 8655701 = 8655864
193 + 8655671 = 8655864
211 + 8655653 = 8655864

Showing the first eight; more decompositions exist.
