Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668906, here are decompositions:

5 + 8668901 = 8668906
17 + 8668889 = 8668906
89 + 8668817 = 8668906
107 + 8668799 = 8668906
167 + 8668739 = 8668906
263 + 8668643 = 8668906
269 + 8668637 = 8668906
293 + 8668613 = 8668906

Showing the first eight; more decompositions exist.
