Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164800, here are decompositions:

11 + 164789 = 164800
29 + 164771 = 164800
71 + 164729 = 164800
137 + 164663 = 164800
173 + 164627 = 164800
179 + 164621 = 164800
269 + 164531 = 164800
353 + 164447 = 164800

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 164,800 and was likely granted around 1874.

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