Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646384, here are decompositions:

7 + 8646377 = 8646384
23 + 8646361 = 8646384
67 + 8646317 = 8646384
107 + 8646277 = 8646384
127 + 8646257 = 8646384
137 + 8646247 = 8646384
151 + 8646233 = 8646384
157 + 8646227 = 8646384

Showing the first eight; more decompositions exist.
