Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8627660, here are decompositions:

43 + 8627617 = 8627660
79 + 8627581 = 8627660
127 + 8627533 = 8627660
157 + 8627503 = 8627660
163 + 8627497 = 8627660
193 + 8627467 = 8627660
229 + 8627431 = 8627660
331 + 8627329 = 8627660

Showing the first eight; more decompositions exist.
