Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646856, here are decompositions:

3 + 8646853 = 8646856
5 + 8646851 = 8646856
137 + 8646719 = 8646856
149 + 8646707 = 8646856
173 + 8646683 = 8646856
353 + 8646503 = 8646856
359 + 8646497 = 8646856
467 + 8646389 = 8646856

Showing the first eight; more decompositions exist.
