Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646828, here are decompositions:

5 + 8646823 = 8646828
7 + 8646821 = 8646828
11 + 8646817 = 8646828
107 + 8646721 = 8646828
109 + 8646719 = 8646828
257 + 8646571 = 8646828
269 + 8646559 = 8646828
317 + 8646511 = 8646828

Showing the first eight; more decompositions exist.
