Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105170, here are decompositions:

3 + 105167 = 105170
73 + 105097 = 105170
139 + 105031 = 105170
151 + 105019 = 105170
199 + 104971 = 105170
211 + 104959 = 105170
223 + 104947 = 105170
367 + 104803 = 105170

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 105,170 and was likely granted around 1870.

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