Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670866, here are decompositions:

3 + 8670863 = 8670866
157 + 8670709 = 8670866
163 + 8670703 = 8670866
199 + 8670667 = 8670866
229 + 8670637 = 8670866
277 + 8670589 = 8670866
283 + 8670583 = 8670866
307 + 8670559 = 8670866

Showing the first eight; more decompositions exist.
