Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655856, here are decompositions:

47 + 8655809 = 8655856
107 + 8655749 = 8655856
137 + 8655719 = 8655856
149 + 8655707 = 8655856
179 + 8655677 = 8655856
227 + 8655629 = 8655856
233 + 8655623 = 8655856
359 + 8655497 = 8655856

Showing the first eight; more decompositions exist.
