Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171398, here are decompositions:

127 + 171271 = 171398
229 + 171169 = 171398
307 + 171091 = 171398
349 + 171049 = 171398
499 + 170899 = 171398
541 + 170857 = 171398
547 + 170851 = 171398
571 + 170827 = 171398

Showing the first eight; more decompositions exist.
