Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171504, here are decompositions:

13 + 171491 = 171504
23 + 171481 = 171504
31 + 171473 = 171504
37 + 171467 = 171504
101 + 171403 = 171504
103 + 171401 = 171504
163 + 171341 = 171504
211 + 171293 = 171504

Showing the first eight; more decompositions exist.
