Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171206, here are decompositions:

3 + 171203 = 171206
37 + 171169 = 171206
43 + 171163 = 171206
103 + 171103 = 171206
127 + 171079 = 171206
157 + 171049 = 171206
163 + 171043 = 171206
199 + 171007 = 171206

Showing the first eight; more decompositions exist.
