Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66566, here are decompositions:

13 + 66553 = 66566
37 + 66529 = 66566
43 + 66523 = 66566
67 + 66499 = 66566
103 + 66463 = 66566
109 + 66457 = 66566
163 + 66403 = 66566
193 + 66373 = 66566

Showing the first eight; more decompositions exist.
