Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188164, here are decompositions:

5 + 188159 = 188164
17 + 188147 = 188164
191 + 187973 = 188164
233 + 187931 = 188164
257 + 187907 = 188164
281 + 187883 = 188164
293 + 187871 = 188164
401 + 187763 = 188164

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 188,164 and was likely granted around 1875.

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