Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171250, here are decompositions:

17 + 171233 = 171250
47 + 171203 = 171250
71 + 171179 = 171250
83 + 171167 = 171250
89 + 171161 = 171250
173 + 171077 = 171250
197 + 171053 = 171250
227 + 171023 = 171250

Showing the first eight; more decompositions exist.
