Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171432, here are decompositions:

5 + 171427 = 171432
29 + 171403 = 171432
31 + 171401 = 171432
103 + 171329 = 171432
139 + 171293 = 171432
179 + 171253 = 171432
181 + 171251 = 171432
199 + 171233 = 171432

Showing the first eight; more decompositions exist.
