Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8676816, here are decompositions:

17 + 8676799 = 8676816
37 + 8676779 = 8676816
47 + 8676769 = 8676816
59 + 8676757 = 8676816
73 + 8676743 = 8676816
97 + 8676719 = 8676816
157 + 8676659 = 8676816
173 + 8676643 = 8676816

Showing the first eight; more decompositions exist.
