Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 170186, here are decompositions:

7 + 170179 = 170186
19 + 170167 = 170186
139 + 170047 = 170186
157 + 170029 = 170186
199 + 169987 = 170186
229 + 169957 = 170186
277 + 169909 = 170186
349 + 169837 = 170186

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 170,186 and was likely granted around 1874.

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