Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166016, here are decompositions:

3 + 166013 = 166016
139 + 165877 = 166016
199 + 165817 = 166016
307 + 165709 = 166016
313 + 165703 = 166016
349 + 165667 = 166016
457 + 165559 = 166016
463 + 165553 = 166016

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 166,016 and was likely granted around 1874.

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