Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643200, here are decompositions:

3 + 8643197 = 8643200
19 + 8643181 = 8643200
67 + 8643133 = 8643200
79 + 8643121 = 8643200
109 + 8643091 = 8643200
211 + 8642989 = 8643200
337 + 8642863 = 8643200
439 + 8642761 = 8643200

Showing the first eight; more decompositions exist.
