Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8650664, here are decompositions:

7 + 8650657 = 8650664
13 + 8650651 = 8650664
31 + 8650633 = 8650664
37 + 8650627 = 8650664
67 + 8650597 = 8650664
103 + 8650561 = 8650664
241 + 8650423 = 8650664
523 + 8650141 = 8650664

Showing the first eight; more decompositions exist.
