Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105158, here are decompositions:

61 + 105097 = 105158
127 + 105031 = 105158
139 + 105019 = 105158
199 + 104959 = 105158
211 + 104947 = 105158
241 + 104917 = 105158
307 + 104851 = 105158
331 + 104827 = 105158

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 105.158 and was likely granted around 1870.

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