Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639798, here are decompositions:

19 + 8639779 = 8639798
151 + 8639647 = 8639798
199 + 8639599 = 8639798
337 + 8639461 = 8639798
397 + 8639401 = 8639798
499 + 8639299 = 8639798
547 + 8639251 = 8639798
571 + 8639227 = 8639798

Showing the first eight; more decompositions exist.
