Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165510, here are decompositions:

31 + 165479 = 165510
41 + 165469 = 165510
47 + 165463 = 165510
53 + 165457 = 165510
61 + 165449 = 165510
67 + 165443 = 165510
73 + 165437 = 165510
113 + 165397 = 165510

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 165,510 and was likely granted around 1874.

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