Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171492, here are decompositions:

11 + 171481 = 171492
19 + 171473 = 171492
23 + 171469 = 171492
43 + 171449 = 171492
53 + 171439 = 171492
89 + 171403 = 171492
109 + 171383 = 171492
151 + 171341 = 171492

Showing the first eight; more decompositions exist.
