Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171252, here are decompositions:

19 + 171233 = 171252
73 + 171179 = 171252
83 + 171169 = 171252
89 + 171163 = 171252
149 + 171103 = 171252
173 + 171079 = 171252
199 + 171053 = 171252
223 + 171029 = 171252

Showing the first eight; more decompositions exist.
