Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 161016, here are decompositions:

7 + 161009 = 161016
19 + 160997 = 161016
47 + 160969 = 161016
83 + 160933 = 161016
109 + 160907 = 161016
113 + 160903 = 161016
137 + 160879 = 161016
139 + 160877 = 161016

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 161,016 and was likely granted around 1874.

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