Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 170550, here are decompositions:

11 + 170539 = 170550
13 + 170537 = 170550
41 + 170509 = 170550
47 + 170503 = 170550
53 + 170497 = 170550
67 + 170483 = 170550
103 + 170447 = 170550
109 + 170441 = 170550

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 170,550 and was likely granted around 1874.

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