Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171384, here are decompositions:

43 + 171341 = 171384
67 + 171317 = 171384
113 + 171271 = 171384
131 + 171253 = 171384
151 + 171233 = 171384
181 + 171203 = 171384
223 + 171161 = 171384
281 + 171103 = 171384

Showing the first eight; more decompositions exist.
