Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 160000, here are decompositions:

23 + 159977 = 160000
89 + 159911 = 160000
101 + 159899 = 160000
131 + 159869 = 160000
167 + 159833 = 160000
227 + 159773 = 160000
263 + 159737 = 160000
293 + 159707 = 160000

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 160,000 and was likely granted around 1873.

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