Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649200, here are decompositions:

3 + 8649197 = 8649200
13 + 8649187 = 8649200
97 + 8649103 = 8649200
139 + 8649061 = 8649200
151 + 8649049 = 8649200
199 + 8649001 = 8649200
271 + 8648929 = 8649200
277 + 8648923 = 8649200

Showing the first eight; more decompositions exist.
