Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 500218, here are decompositions:

41 + 500177 = 500218
107 + 500111 = 500218
149 + 500069 = 500218
239 + 499979 = 500218
431 + 499787 = 500218
479 + 499739 = 500218
557 + 499661 = 500218
569 + 499649 = 500218

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 500,218 and was likely granted around 1893.

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