Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171318, here are decompositions:

19 + 171299 = 171318
47 + 171271 = 171318
67 + 171251 = 171318
139 + 171179 = 171318
149 + 171169 = 171318
151 + 171167 = 171318
157 + 171161 = 171318
227 + 171091 = 171318

Showing the first eight; more decompositions exist.
