Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164550, here are decompositions:

19 + 164531 = 164550
37 + 164513 = 164550
47 + 164503 = 164550
73 + 164477 = 164550
79 + 164471 = 164550
101 + 164449 = 164550
103 + 164447 = 164550
107 + 164443 = 164550

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 164,550 and was likely granted around 1874.

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