Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171606, here are decompositions:

23 + 171583 = 171606
47 + 171559 = 171606
53 + 171553 = 171606
67 + 171539 = 171606
89 + 171517 = 171606
137 + 171469 = 171606
139 + 171467 = 171606
157 + 171449 = 171606

Showing the first eight; more decompositions exist.
