Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8651008, here are decompositions:

11 + 8650997 = 8651008
29 + 8650979 = 8651008
89 + 8650919 = 8651008
281 + 8650727 = 8651008
449 + 8650559 = 8651008
467 + 8650541 = 8651008
491 + 8650517 = 8651008
521 + 8650487 = 8651008

Showing the first eight; more decompositions exist.
