Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 170658, here are decompositions:

11 + 170647 = 170658
17 + 170641 = 170658
31 + 170627 = 170658
79 + 170579 = 170658
101 + 170557 = 170658
107 + 170551 = 170658
149 + 170509 = 170658
211 + 170447 = 170658

Showing the first eight; more decompositions exist.

Possible US patent number

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 170,658 and was likely granted around 1874.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
