Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 179900, here are decompositions:

3 + 179897 = 179900
67 + 179833 = 179900
73 + 179827 = 179900
79 + 179821 = 179900
151 + 179749 = 179900
157 + 179743 = 179900
163 + 179737 = 179900
181 + 179719 = 179900

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 179,900 and was likely granted around 1875.

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