Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171490, here are decompositions:

17 + 171473 = 171490
23 + 171467 = 171490
41 + 171449 = 171490
89 + 171401 = 171490
107 + 171383 = 171490
149 + 171341 = 171490
173 + 171317 = 171490
191 + 171299 = 171490

Showing the first eight; more decompositions exist.
