Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 500420, here are decompositions:

3 + 500417 = 500420
7 + 500413 = 500420
31 + 500389 = 500420
79 + 500341 = 500420
103 + 500317 = 500420
163 + 500257 = 500420
181 + 500239 = 500420
211 + 500209 = 500420

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 500,420 and was likely granted around 1893.

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