Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643976, here are decompositions:

17 + 8643959 = 8643976
23 + 8643953 = 8643976
53 + 8643923 = 8643976
83 + 8643893 = 8643976
137 + 8643839 = 8643976
179 + 8643797 = 8643976
197 + 8643779 = 8643976
227 + 8643749 = 8643976

Showing the first eight; more decompositions exist.
