Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171486, here are decompositions:

5 + 171481 = 171486
13 + 171473 = 171486
17 + 171469 = 171486
19 + 171467 = 171486
37 + 171449 = 171486
47 + 171439 = 171486
59 + 171427 = 171486
83 + 171403 = 171486

Showing the first eight; more decompositions exist.
