Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28568, here are decompositions:

19 + 28549 = 28568
31 + 28537 = 28568
139 + 28429 = 28568
157 + 28411 = 28568
181 + 28387 = 28568
271 + 28297 = 28568
349 + 28219 = 28568
367 + 28201 = 28568

Showing the first eight; more decompositions exist.
