Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171590, here are decompositions:

7 + 171583 = 171590
19 + 171571 = 171590
31 + 171559 = 171590
37 + 171553 = 171590
61 + 171529 = 171590
73 + 171517 = 171590
109 + 171481 = 171590
151 + 171439 = 171590

Showing the first eight; more decompositions exist.
