Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171342, here are decompositions:

13 + 171329 = 171342
43 + 171299 = 171342
71 + 171271 = 171342
79 + 171263 = 171342
89 + 171253 = 171342
109 + 171233 = 171342
139 + 171203 = 171342
163 + 171179 = 171342

Showing the first eight; more decompositions exist.
