Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 170668, here are decompositions:

41 + 170627 = 170668
59 + 170609 = 170668
89 + 170579 = 170668
131 + 170537 = 170668
227 + 170441 = 170668
317 + 170351 = 170668
389 + 170279 = 170668
401 + 170267 = 170668

Showing the first eight; more decompositions exist.
