Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718660, here are decompositions:

11 + 8718649 = 8718660
59 + 8718601 = 8718660
79 + 8718581 = 8718660
89 + 8718571 = 8718660
157 + 8718503 = 8718660
173 + 8718487 = 8718660
191 + 8718469 = 8718660
199 + 8718461 = 8718660

Showing the first eight; more decompositions exist.
