Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 161416, here are decompositions:

5 + 161411 = 161416
29 + 161387 = 161416
53 + 161363 = 161416
83 + 161333 = 161416
107 + 161309 = 161416
113 + 161303 = 161416
149 + 161267 = 161416
179 + 161237 = 161416

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 161,416 and was likely granted around 1874.

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