Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 170920, here are decompositions:

47 + 170873 = 170920
83 + 170837 = 170920
107 + 170813 = 170920
179 + 170741 = 170920
251 + 170669 = 170920
293 + 170627 = 170920
311 + 170609 = 170920
317 + 170603 = 170920

Showing the first eight; more decompositions exist.
