Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171532, here are decompositions:

3 + 171529 = 171532
41 + 171491 = 171532
59 + 171473 = 171532
83 + 171449 = 171532
131 + 171401 = 171532
149 + 171383 = 171532
191 + 171341 = 171532
233 + 171299 = 171532

Showing the first eight; more decompositions exist.
