Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171290, here are decompositions:

19 + 171271 = 171290
37 + 171253 = 171290
127 + 171163 = 171290
199 + 171091 = 171290
211 + 171079 = 171290
241 + 171049 = 171290
283 + 171007 = 171290
337 + 170953 = 171290

Showing the first eight; more decompositions exist.
