Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655928, here are decompositions:

5 + 8655923 = 8655928
11 + 8655917 = 8655928
59 + 8655869 = 8655928
167 + 8655761 = 8655928
179 + 8655749 = 8655928
227 + 8655701 = 8655928
251 + 8655677 = 8655928
257 + 8655671 = 8655928

Showing the first eight; more decompositions exist.
