Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501406, here are decompositions:

5 + 501401 = 501406
23 + 501383 = 501406
89 + 501317 = 501406
107 + 501299 = 501406
149 + 501257 = 501406
173 + 501233 = 501406
197 + 501209 = 501406
233 + 501173 = 501406

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 501,406 and was likely granted around 1893.

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