Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171436, here are decompositions:

53 + 171383 = 171436
107 + 171329 = 171436
137 + 171299 = 171436
173 + 171263 = 171436
233 + 171203 = 171436
257 + 171179 = 171436
269 + 171167 = 171436
359 + 171077 = 171436

Showing the first eight; more decompositions exist.
