Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22566, here are decompositions:

17 + 22549 = 22566
23 + 22543 = 22566
83 + 22483 = 22566
97 + 22469 = 22566
113 + 22453 = 22566
157 + 22409 = 22566
197 + 22369 = 22566
199 + 22367 = 22566

Showing the first eight; more decompositions exist.
