Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8627780, here are decompositions:

3 + 8627777 = 8627780
67 + 8627713 = 8627780
79 + 8627701 = 8627780
163 + 8627617 = 8627780
199 + 8627581 = 8627780
211 + 8627569 = 8627780
277 + 8627503 = 8627780
283 + 8627497 = 8627780

Showing the first eight; more decompositions exist.
