Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655018, here are decompositions:

7 + 8655011 = 8655018
11 + 8655007 = 8655018
37 + 8654981 = 8655018
59 + 8654959 = 8655018
101 + 8654917 = 8655018
179 + 8654839 = 8655018
181 + 8654837 = 8655018
257 + 8654761 = 8655018

Showing the first eight; more decompositions exist.
