Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656018, here are decompositions:

101 + 8655917 = 8656018
149 + 8655869 = 8656018
257 + 8655761 = 8656018
269 + 8655749 = 8656018
311 + 8655707 = 8656018
317 + 8655701 = 8656018
347 + 8655671 = 8656018
389 + 8655629 = 8656018

Showing the first eight; more decompositions exist.
