Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171282, here are decompositions:

11 + 171271 = 171282
19 + 171263 = 171282
29 + 171253 = 171282
31 + 171251 = 171282
79 + 171203 = 171282
103 + 171179 = 171282
113 + 171169 = 171282
151 + 171131 = 171282

Showing the first eight; more decompositions exist.
