Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171568, here are decompositions:

29 + 171539 = 171568
101 + 171467 = 171568
167 + 171401 = 171568
227 + 171341 = 171568
239 + 171329 = 171568
251 + 171317 = 171568
269 + 171299 = 171568
317 + 171251 = 171568

Showing the first eight; more decompositions exist.
