Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16568, here are decompositions:

7 + 16561 = 16568
151 + 16417 = 16568
157 + 16411 = 16568
199 + 16369 = 16568
229 + 16339 = 16568
337 + 16231 = 16568
379 + 16189 = 16568
457 + 16111 = 16568

Showing the first eight; more decompositions exist.
