Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164018, here are decompositions:

7 + 164011 = 164018
31 + 163987 = 164018
37 + 163981 = 164018
109 + 163909 = 164018
157 + 163861 = 164018
199 + 163819 = 164018
229 + 163789 = 164018
277 + 163741 = 164018

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 164,018 and was likely granted around 1874.

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