Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643998, here are decompositions:

7 + 8643991 = 8643998
79 + 8643919 = 8643998
109 + 8643889 = 8643998
211 + 8643787 = 8643998
241 + 8643757 = 8643998
277 + 8643721 = 8643998
367 + 8643631 = 8643998
379 + 8643619 = 8643998

Showing the first eight; more decompositions exist.
