Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655918, here are decompositions:

17 + 8655901 = 8655918
41 + 8655877 = 8655918
59 + 8655859 = 8655918
109 + 8655809 = 8655918
149 + 8655769 = 8655918
157 + 8655761 = 8655918
179 + 8655739 = 8655918
197 + 8655721 = 8655918

Showing the first eight; more decompositions exist.
