Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171170, here are decompositions:

3 + 171167 = 171170
7 + 171163 = 171170
67 + 171103 = 171170
79 + 171091 = 171170
127 + 171043 = 171170
163 + 171007 = 171170
199 + 170971 = 171170
271 + 170899 = 171170

Showing the first eight; more decompositions exist.
