Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100860, here are decompositions:

7 + 100853 = 100860
13 + 100847 = 100860
31 + 100829 = 100860
37 + 100823 = 100860
59 + 100801 = 100860
61 + 100799 = 100860
73 + 100787 = 100860
113 + 100747 = 100860

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 100,860 and was likely granted around 1870.

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