Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655816, here are decompositions:

7 + 8655809 = 8655816
47 + 8655769 = 8655816
67 + 8655749 = 8655816
83 + 8655733 = 8655816
97 + 8655719 = 8655816
109 + 8655707 = 8655816
137 + 8655679 = 8655816
139 + 8655677 = 8655816

Showing the first eight; more decompositions exist.
