Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171270, here are decompositions:

7 + 171263 = 171270
17 + 171253 = 171270
19 + 171251 = 171270
37 + 171233 = 171270
67 + 171203 = 171270
101 + 171169 = 171270
103 + 171167 = 171270
107 + 171163 = 171270

Showing the first eight; more decompositions exist.
