Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668994, here are decompositions:

43 + 8668951 = 8668994
97 + 8668897 = 8668994
157 + 8668837 = 8668994
163 + 8668831 = 8668994
181 + 8668813 = 8668994
193 + 8668801 = 8668994
211 + 8668783 = 8668994
283 + 8668711 = 8668994

Showing the first eight; more decompositions exist.
