Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644008, here are decompositions:

11 + 8643997 = 8644008
17 + 8643991 = 8644008
67 + 8643941 = 8644008
89 + 8643919 = 8644008
157 + 8643851 = 8644008
211 + 8643797 = 8644008
229 + 8643779 = 8644008
251 + 8643757 = 8644008

Showing the first eight; more decompositions exist.
