Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171086, here are decompositions:

7 + 171079 = 171086
37 + 171049 = 171086
43 + 171043 = 171086
79 + 171007 = 171086
199 + 170887 = 171086
229 + 170857 = 171086
277 + 170809 = 171086
313 + 170773 = 171086

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 171,086 and was likely granted around 1874.

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