Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16562, here are decompositions:

43 + 16519 = 16562
109 + 16453 = 16562
151 + 16411 = 16562
181 + 16381 = 16562
193 + 16369 = 16562
199 + 16363 = 16562
223 + 16339 = 16562
229 + 16333 = 16562

Showing the first eight; more decompositions exist.
