Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 173800, here are decompositions:

17 + 173783 = 173800
23 + 173777 = 173800
59 + 173741 = 173800
71 + 173729 = 173800
101 + 173699 = 173800
113 + 173687 = 173800
131 + 173669 = 173800
149 + 173651 = 173800

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 173,800 and was likely granted around 1874.

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