Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655760, here are decompositions:

11 + 8655749 = 8655760
41 + 8655719 = 8655760
53 + 8655707 = 8655760
59 + 8655701 = 8655760
83 + 8655677 = 8655760
89 + 8655671 = 8655760
107 + 8655653 = 8655760
131 + 8655629 = 8655760

Showing the first eight; more decompositions exist.
