Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646470, here are decompositions:

13 + 8646457 = 8646470
67 + 8646403 = 8646470
109 + 8646361 = 8646470
193 + 8646277 = 8646470
211 + 8646259 = 8646470
223 + 8646247 = 8646470
307 + 8646163 = 8646470
367 + 8646103 = 8646470

Showing the first eight; more decompositions exist.
