Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171582, here are decompositions:

11 + 171571 = 171582
23 + 171559 = 171582
29 + 171553 = 171582
41 + 171541 = 171582
43 + 171539 = 171582
53 + 171529 = 171582
101 + 171481 = 171582
109 + 171473 = 171582

Showing the first eight; more decompositions exist.
