Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668940, here are decompositions:

43 + 8668897 = 8668940
67 + 8668873 = 8668940
103 + 8668837 = 8668940
109 + 8668831 = 8668940
127 + 8668813 = 8668940
139 + 8668801 = 8668940
157 + 8668783 = 8668940
199 + 8668741 = 8668940

Showing the first eight; more decompositions exist.
