Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8650668, here are decompositions:

11 + 8650657 = 8650668
17 + 8650651 = 8650668
41 + 8650627 = 8650668
71 + 8650597 = 8650668
107 + 8650561 = 8650668
109 + 8650559 = 8650668
127 + 8650541 = 8650668
137 + 8650531 = 8650668

Showing the first eight; more decompositions exist.
