Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668900, here are decompositions:

3 + 8668897 = 8668900
11 + 8668889 = 8668900
83 + 8668817 = 8668900
101 + 8668799 = 8668900
137 + 8668763 = 8668900
179 + 8668721 = 8668900
257 + 8668643 = 8668900
263 + 8668637 = 8668900

Showing the first eight; more decompositions exist.
