Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 522100, here are decompositions:

17 + 522083 = 522100
41 + 522059 = 522100
53 + 522047 = 522100
83 + 522017 = 522100
101 + 521999 = 522100
107 + 521993 = 522100
197 + 521903 = 522100
239 + 521861 = 522100

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 522,100 and was likely granted around 1894.

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