Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164188, here are decompositions:

5 + 164183 = 164188
41 + 164147 = 164188
71 + 164117 = 164188
131 + 164057 = 164188
137 + 164051 = 164188
149 + 164039 = 164188
191 + 163997 = 164188
197 + 163991 = 164188

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 164,188 and was likely granted around 1874.

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