Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171628, here are decompositions:

11 + 171617 = 171628
89 + 171539 = 171628
137 + 171491 = 171628
179 + 171449 = 171628
227 + 171401 = 171628
311 + 171317 = 171628
449 + 171179 = 171628
461 + 171167 = 171628

Showing the first eight; more decompositions exist.
