Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171328, here are decompositions:

11 + 171317 = 171328
29 + 171299 = 171328
149 + 171179 = 171328
167 + 171161 = 171328
197 + 171131 = 171328
251 + 171077 = 171328
281 + 171047 = 171328
401 + 170927 = 171328

Showing the first eight; more decompositions exist.
