Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643300, here are decompositions:

13 + 8643287 = 8643300
19 + 8643281 = 8643300
89 + 8643211 = 8643300
101 + 8643199 = 8643300
103 + 8643197 = 8643300
151 + 8643149 = 8643300
157 + 8643143 = 8643300
163 + 8643137 = 8643300

Showing the first eight; more decompositions exist.
