Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655988, here are decompositions:

71 + 8655917 = 8655988
179 + 8655809 = 8655988
227 + 8655761 = 8655988
239 + 8655749 = 8655988
269 + 8655719 = 8655988
281 + 8655707 = 8655988
311 + 8655677 = 8655988
317 + 8655671 = 8655988

Showing the first eight; more decompositions exist.
