Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647328, here are decompositions:

97 + 8647231 = 8647328
199 + 8647129 = 8647328
307 + 8647021 = 8647328
367 + 8646961 = 8647328
379 + 8646949 = 8647328
439 + 8646889 = 8647328
577 + 8646751 = 8647328
607 + 8646721 = 8647328

Showing the first eight; more decompositions exist.
