Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171320, here are decompositions:

3 + 171317 = 171320
67 + 171253 = 171320
151 + 171169 = 171320
157 + 171163 = 171320
229 + 171091 = 171320
241 + 171079 = 171320
271 + 171049 = 171320
277 + 171043 = 171320

Showing the first eight; more decompositions exist.
