Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656618, here are decompositions:

29 + 8656589 = 8656618
41 + 8656577 = 8656618
71 + 8656547 = 8656618
101 + 8656517 = 8656618
107 + 8656511 = 8656618
137 + 8656481 = 8656618
149 + 8656469 = 8656618
239 + 8656379 = 8656618

Showing the first eight; more decompositions exist.
