Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164810, here are decompositions:

43 + 164767 = 164810
67 + 164743 = 164810
103 + 164707 = 164810
109 + 164701 = 164810
127 + 164683 = 164810
157 + 164653 = 164810
193 + 164617 = 164810
211 + 164599 = 164810

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 164,810 and was likely granted around 1874.

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