Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643006, here are decompositions:

17 + 8642989 = 8643006
59 + 8642947 = 8643006
67 + 8642939 = 8643006
79 + 8642927 = 8643006
103 + 8642903 = 8643006
109 + 8642897 = 8643006
149 + 8642857 = 8643006
157 + 8642849 = 8643006

Showing the first eight; more decompositions exist.
