Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668870, here are decompositions:

53 + 8668817 = 8668870
71 + 8668799 = 8668870
107 + 8668763 = 8668870
131 + 8668739 = 8668870
149 + 8668721 = 8668870
173 + 8668697 = 8668870
227 + 8668643 = 8668870
233 + 8668637 = 8668870

Showing the first eight; more decompositions exist.
