Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171506, here are decompositions:

37 + 171469 = 171506
67 + 171439 = 171506
79 + 171427 = 171506
103 + 171403 = 171506
337 + 171169 = 171506
457 + 171049 = 171506
463 + 171043 = 171506
499 + 171007 = 171506

Showing the first eight; more decompositions exist.
