Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100858, here are decompositions:

5 + 100853 = 100858
11 + 100847 = 100858
29 + 100829 = 100858
47 + 100811 = 100858
59 + 100799 = 100858
71 + 100787 = 100858
89 + 100769 = 100858
311 + 100547 = 100858

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 100,858 and was likely granted around 1870.

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