Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628000, here are decompositions:

13 + 8627987 = 8628000
23 + 8627977 = 8628000
47 + 8627953 = 8628000
53 + 8627947 = 8628000
61 + 8627939 = 8628000
89 + 8627911 = 8628000
97 + 8627903 = 8628000
103 + 8627897 = 8628000

Showing the first eight; more decompositions exist.
