Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646584, here are decompositions:

3 + 8646581 = 8646584
13 + 8646571 = 8646584
73 + 8646511 = 8646584
97 + 8646487 = 8646584
127 + 8646457 = 8646584
181 + 8646403 = 8646584
223 + 8646361 = 8646584
307 + 8646277 = 8646584

Showing the first eight; more decompositions exist.
