Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668966, here are decompositions:

149 + 8668817 = 8668966
167 + 8668799 = 8668966
227 + 8668739 = 8668966
269 + 8668697 = 8668966
353 + 8668613 = 8668966
389 + 8668577 = 8668966
419 + 8668547 = 8668966
443 + 8668523 = 8668966

Showing the first eight; more decompositions exist.
