Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521050, here are decompositions:

3 + 521047 = 521050
11 + 521039 = 521050
29 + 521021 = 521050
41 + 521009 = 521050
83 + 520967 = 521050
107 + 520943 = 521050
137 + 520913 = 521050
197 + 520853 = 521050

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 521,050 and was likely granted around 1894.

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