Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646684, here are decompositions:

17 + 8646667 = 8646684
103 + 8646581 = 8646684
113 + 8646571 = 8646684
173 + 8646511 = 8646684
181 + 8646503 = 8646684
197 + 8646487 = 8646684
227 + 8646457 = 8646684
281 + 8646403 = 8646684

Showing the first eight; more decompositions exist.
