Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 500018, here are decompositions:

61 + 499957 = 500018
139 + 499879 = 500018
199 + 499819 = 500018
271 + 499747 = 500018
307 + 499711 = 500018
331 + 499687 = 500018
349 + 499669 = 500018
397 + 499621 = 500018

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 500,018 and was likely granted around 1893.

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