Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640200, here are decompositions:

3 + 8640197 = 8640200
13 + 8640187 = 8640200
31 + 8640169 = 8640200
67 + 8640133 = 8640200
199 + 8640001 = 8640200
223 + 8639977 = 8640200
277 + 8639923 = 8640200
337 + 8639863 = 8640200

Showing the first eight; more decompositions exist.
