Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105868, here are decompositions:

5 + 105863 = 105868
101 + 105767 = 105868
107 + 105761 = 105868
167 + 105701 = 105868
311 + 105557 = 105868
359 + 105509 = 105868
401 + 105467 = 105868
419 + 105449 = 105868

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 105.868 and was likely granted around 1870.

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