Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13568, here are decompositions:

31 + 13537 = 13568
127 + 13441 = 13568
151 + 13417 = 13568
157 + 13411 = 13568
229 + 13339 = 13568
241 + 13327 = 13568
271 + 13297 = 13568
277 + 13291 = 13568

Showing the first eight; more decompositions exist.
