Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 170180, here are decompositions:

13 + 170167 = 170180
79 + 170101 = 170180
151 + 170029 = 170180
193 + 169987 = 170180
223 + 169957 = 170180
229 + 169951 = 170180
271 + 169909 = 170180
337 + 169843 = 170180

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 170,180 and was likely granted around 1874.

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