Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171258, here are decompositions:

5 + 171253 = 171258
7 + 171251 = 171258
79 + 171179 = 171258
89 + 171169 = 171258
97 + 171161 = 171258
127 + 171131 = 171258
167 + 171091 = 171258
179 + 171079 = 171258

Showing the first eight; more decompositions exist.
