Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171426, here are decompositions:

23 + 171403 = 171426
43 + 171383 = 171426
97 + 171329 = 171426
109 + 171317 = 171426
127 + 171299 = 171426
163 + 171263 = 171426
173 + 171253 = 171426
193 + 171233 = 171426

Showing the first eight; more decompositions exist.
