Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646606, here are decompositions:

47 + 8646559 = 8646606
103 + 8646503 = 8646606
109 + 8646497 = 8646606
127 + 8646479 = 8646606
149 + 8646457 = 8646606
229 + 8646377 = 8646606
277 + 8646329 = 8646606
307 + 8646299 = 8646606

Showing the first eight; more decompositions exist.
