Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17568, here are decompositions:

17 + 17551 = 17568
29 + 17539 = 17568
59 + 17509 = 17568
71 + 17497 = 17568
79 + 17489 = 17568
97 + 17471 = 17568
101 + 17467 = 17568
137 + 17431 = 17568

Showing the first eight; more decompositions exist.
