Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171588, here are decompositions:

5 + 171583 = 171588
17 + 171571 = 171588
29 + 171559 = 171588
47 + 171541 = 171588
59 + 171529 = 171588
71 + 171517 = 171588
97 + 171491 = 171588
107 + 171481 = 171588

Showing the first eight; more decompositions exist.
