Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666630, here are decompositions:

3 + 8666627 = 8666630
97 + 8666533 = 8666630
139 + 8666491 = 8666630
151 + 8666479 = 8666630
199 + 8666431 = 8666630
211 + 8666419 = 8666630
283 + 8666347 = 8666630
307 + 8666323 = 8666630

Showing the first eight; more decompositions exist.
