Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655858, here are decompositions:

17 + 8655841 = 8655858
89 + 8655769 = 8655858
97 + 8655761 = 8655858
109 + 8655749 = 8655858
137 + 8655721 = 8655858
139 + 8655719 = 8655858
151 + 8655707 = 8655858
157 + 8655701 = 8655858

Showing the first eight; more decompositions exist.
