Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171406, here are decompositions:

3 + 171403 = 171406
5 + 171401 = 171406
23 + 171383 = 171406
89 + 171317 = 171406
107 + 171299 = 171406
113 + 171293 = 171406
173 + 171233 = 171406
227 + 171179 = 171406

Showing the first eight; more decompositions exist.
