Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105164, here are decompositions:

67 + 105097 = 105164
127 + 105037 = 105164
193 + 104971 = 105164
211 + 104953 = 105164
313 + 104851 = 105164
337 + 104827 = 105164
421 + 104743 = 105164
457 + 104707 = 105164

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 105,164 and was likely granted around 1870.

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