Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647298, here are decompositions:

67 + 8647231 = 8647298
271 + 8647027 = 8647298
277 + 8647021 = 8647298
337 + 8646961 = 8647298
349 + 8646949 = 8647298
409 + 8646889 = 8647298
547 + 8646751 = 8647298
577 + 8646721 = 8647298

Showing the first eight; more decompositions exist.
