Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646816, here are decompositions:

23 + 8646793 = 8646816
37 + 8646779 = 8646816
97 + 8646719 = 8646816
107 + 8646709 = 8646816
109 + 8646707 = 8646816
149 + 8646667 = 8646816
257 + 8646559 = 8646816
313 + 8646503 = 8646816

Showing the first eight; more decompositions exist.
