Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171470, here are decompositions:

3 + 171467 = 171470
31 + 171439 = 171470
43 + 171427 = 171470
67 + 171403 = 171470
199 + 171271 = 171470
307 + 171163 = 171470
367 + 171103 = 171470
379 + 171091 = 171470

Showing the first eight; more decompositions exist.
