Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171210, here are decompositions:

7 + 171203 = 171210
31 + 171179 = 171210
41 + 171169 = 171210
43 + 171167 = 171210
47 + 171163 = 171210
79 + 171131 = 171210
107 + 171103 = 171210
131 + 171079 = 171210

Showing the first eight; more decompositions exist.
