Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645008, here are decompositions:

17 + 8644991 = 8645008
59 + 8644949 = 8645008
89 + 8644919 = 8645008
227 + 8644781 = 8645008
257 + 8644751 = 8645008
347 + 8644661 = 8645008
401 + 8644607 = 8645008
479 + 8644529 = 8645008

Showing the first eight; more decompositions exist.
