Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171284, here are decompositions:

13 + 171271 = 171284
31 + 171253 = 171284
181 + 171103 = 171284
193 + 171091 = 171284
241 + 171043 = 171284
277 + 171007 = 171284
313 + 170971 = 171284
331 + 170953 = 171284

Showing the first eight; more decompositions exist.
