Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643008, here are decompositions:

19 + 8642989 = 8643008
61 + 8642947 = 8643008
97 + 8642911 = 8643008
151 + 8642857 = 8643008
499 + 8642509 = 8643008
541 + 8642467 = 8643008
727 + 8642281 = 8643008
811 + 8642197 = 8643008

Showing the first eight; more decompositions exist.
