Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12568, here are decompositions:

29 + 12539 = 12568
41 + 12527 = 12568
71 + 12497 = 12568
89 + 12479 = 12568
131 + 12437 = 12568
167 + 12401 = 12568
191 + 12377 = 12568
239 + 12329 = 12568

Showing the first eight; more decompositions exist.
