Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164500, here are decompositions:

23 + 164477 = 164500
29 + 164471 = 164500
53 + 164447 = 164500
71 + 164429 = 164500
113 + 164387 = 164500
137 + 164363 = 164500
179 + 164321 = 164500
191 + 164309 = 164500

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 164,500 and was likely granted around 1874.

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