Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655768, here are decompositions:

7 + 8655761 = 8655768
19 + 8655749 = 8655768
29 + 8655739 = 8655768
47 + 8655721 = 8655768
61 + 8655707 = 8655768
67 + 8655701 = 8655768
89 + 8655679 = 8655768
97 + 8655671 = 8655768

Showing the first eight; more decompositions exist.
