Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648000, here are decompositions:

3 + 8647997 = 8648000
7 + 8647993 = 8648000
37 + 8647963 = 8648000
73 + 8647927 = 8648000
103 + 8647897 = 8648000
181 + 8647819 = 8648000
199 + 8647801 = 8648000
241 + 8647759 = 8648000

Showing the first eight; more decompositions exist.
