Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105870, here are decompositions:

7 + 105863 = 105870
41 + 105829 = 105870
53 + 105817 = 105870
101 + 105769 = 105870
103 + 105767 = 105870
109 + 105761 = 105870
137 + 105733 = 105870
179 + 105691 = 105870

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 105.870 and was likely granted around 1870.

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