Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646344, here are decompositions:

67 + 8646277 = 8646344
97 + 8646247 = 8646344
163 + 8646181 = 8646344
181 + 8646163 = 8646344
241 + 8646103 = 8646344
283 + 8646061 = 8646344
373 + 8645971 = 8646344
457 + 8645887 = 8646344

Showing the first eight; more decompositions exist.
