Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8627618, here are decompositions:

7 + 8627611 = 8627618
37 + 8627581 = 8627618
151 + 8627467 = 8627618
277 + 8627341 = 8627618
367 + 8627251 = 8627618
457 + 8627161 = 8627618
499 + 8627119 = 8627618
619 + 8626999 = 8627618

Showing the first eight; more decompositions exist.
