Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639924, here are decompositions:

3 + 8639921 = 8639924
61 + 8639863 = 8639924
127 + 8639797 = 8639924
151 + 8639773 = 8639924
211 + 8639713 = 8639924
277 + 8639647 = 8639924
373 + 8639551 = 8639924
463 + 8639461 = 8639924

Showing the first eight; more decompositions exist.
