Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171202, here are decompositions:

23 + 171179 = 171202
41 + 171161 = 171202
71 + 171131 = 171202
149 + 171053 = 171202
173 + 171029 = 171202
179 + 171023 = 171202
281 + 170921 = 171202
359 + 170843 = 171202

Showing the first eight; more decompositions exist.
