Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15568, here are decompositions:

17 + 15551 = 15568
41 + 15527 = 15568
71 + 15497 = 15568
101 + 15467 = 15568
107 + 15461 = 15568
167 + 15401 = 15568
191 + 15377 = 15568
239 + 15329 = 15568

Showing the first eight; more decompositions exist.
