Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521950, here are decompositions:

47 + 521903 = 521950
53 + 521897 = 521950
71 + 521879 = 521950
89 + 521861 = 521950
131 + 521819 = 521950
137 + 521813 = 521950
173 + 521777 = 521950
197 + 521753 = 521950

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 521,950 and was likely granted around 1894.

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