Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171586, here are decompositions:

3 + 171583 = 171586
47 + 171539 = 171586
113 + 171473 = 171586
137 + 171449 = 171586
257 + 171329 = 171586
269 + 171317 = 171586
293 + 171293 = 171586
353 + 171233 = 171586

Showing the first eight; more decompositions exist.
