Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 186100, here are decompositions:

3 + 186097 = 186100
29 + 186071 = 186100
59 + 186041 = 186100
107 + 185993 = 186100
113 + 185987 = 186100
149 + 185951 = 186100
197 + 185903 = 186100
227 + 185873 = 186100

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 186,100 and was likely granted around 1875.

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