Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643000, here are decompositions:

11 + 8642989 = 8643000
53 + 8642947 = 8643000
61 + 8642939 = 8643000
73 + 8642927 = 8643000
89 + 8642911 = 8643000
97 + 8642903 = 8643000
103 + 8642897 = 8643000
137 + 8642863 = 8643000

Showing the first eight; more decompositions exist.
