Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643332, here are decompositions:

109 + 8643223 = 8643332
151 + 8643181 = 8643332
199 + 8643133 = 8643332
211 + 8643121 = 8643332
223 + 8643109 = 8643332
241 + 8643091 = 8643332
421 + 8642911 = 8643332
571 + 8642761 = 8643332

Showing the first eight; more decompositions exist.
