Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 161314, here are decompositions:

5 + 161309 = 161314
11 + 161303 = 161314
47 + 161267 = 161314
113 + 161201 = 161314
173 + 161141 = 161314
191 + 161123 = 161314
227 + 161087 = 161314
281 + 161033 = 161314

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 161,314 and was likely granted around 1874.

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