Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 170386, here are decompositions:

3 + 170383 = 170386
17 + 170369 = 170386
23 + 170363 = 170386
59 + 170327 = 170386
107 + 170279 = 170386
137 + 170249 = 170386
173 + 170213 = 170386
179 + 170207 = 170386

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 170,386 and was likely granted around 1874.

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