Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16566, here are decompositions:

5 + 16561 = 16566
13 + 16553 = 16566
19 + 16547 = 16566
37 + 16529 = 16566
47 + 16519 = 16566
73 + 16493 = 16566
79 + 16487 = 16566
89 + 16477 = 16566

Showing the first eight; more decompositions exist.
