Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8676780, here are decompositions:

11 + 8676769 = 8676780
23 + 8676757 = 8676780
29 + 8676751 = 8676780
37 + 8676743 = 8676780
59 + 8676721 = 8676780
61 + 8676719 = 8676780
89 + 8676691 = 8676780
137 + 8676643 = 8676780

Showing the first eight; more decompositions exist.
