Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8606646, here are decompositions:

43 + 8606603 = 8606646
47 + 8606599 = 8606646
89 + 8606557 = 8606646
109 + 8606537 = 8606646
137 + 8606509 = 8606646
193 + 8606453 = 8606646
199 + 8606447 = 8606646
233 + 8606413 = 8606646

Showing the first eight; more decompositions exist.
