Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668944, here are decompositions:

43 + 8668901 = 8668944
47 + 8668897 = 8668944
71 + 8668873 = 8668944
107 + 8668837 = 8668944
113 + 8668831 = 8668944
127 + 8668817 = 8668944
131 + 8668813 = 8668944
181 + 8668763 = 8668944

Showing the first eight; more decompositions exist.
