Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171558, here are decompositions:

5 + 171553 = 171558
17 + 171541 = 171558
19 + 171539 = 171558
29 + 171529 = 171558
41 + 171517 = 171558
67 + 171491 = 171558
89 + 171469 = 171558
109 + 171449 = 171558

Showing the first eight; more decompositions exist.
