Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171450, here are decompositions:

11 + 171439 = 171450
23 + 171427 = 171450
47 + 171403 = 171450
67 + 171383 = 171450
109 + 171341 = 171450
151 + 171299 = 171450
157 + 171293 = 171450
179 + 171271 = 171450

Showing the first eight; more decompositions exist.
