Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646554, here are decompositions:

43 + 8646511 = 8646554
67 + 8646487 = 8646554
97 + 8646457 = 8646554
151 + 8646403 = 8646554
193 + 8646361 = 8646554
277 + 8646277 = 8646554
307 + 8646247 = 8646554
331 + 8646223 = 8646554

Showing the first eight; more decompositions exist.
