Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668956, here are decompositions:

5 + 8668951 = 8668956
59 + 8668897 = 8668956
67 + 8668889 = 8668956
83 + 8668873 = 8668956
139 + 8668817 = 8668956
157 + 8668799 = 8668956
173 + 8668783 = 8668956
193 + 8668763 = 8668956

Showing the first eight; more decompositions exist.
