Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639996, here are decompositions:

19 + 8639977 = 8639996
73 + 8639923 = 8639996
97 + 8639899 = 8639996
193 + 8639803 = 8639996
199 + 8639797 = 8639996
223 + 8639773 = 8639996
283 + 8639713 = 8639996
349 + 8639647 = 8639996

Showing the first eight; more decompositions exist.
