Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 522000, here are decompositions:

7 + 521993 = 522000
19 + 521981 = 522000
71 + 521929 = 522000
97 + 521903 = 522000
103 + 521897 = 522000
113 + 521887 = 522000
131 + 521869 = 522000
139 + 521861 = 522000

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 522,000 and was likely granted around 1894.

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