Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656566, here are decompositions:

5 + 8656561 = 8656566
19 + 8656547 = 8656566
29 + 8656537 = 8656566
43 + 8656523 = 8656566
67 + 8656499 = 8656566
73 + 8656493 = 8656566
89 + 8656477 = 8656566
97 + 8656469 = 8656566

Showing the first eight; more decompositions exist.
