Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518000, here are decompositions:

19 + 517981 = 518000
73 + 517927 = 518000
127 + 517873 = 518000
139 + 517861 = 518000
271 + 517729 = 518000
283 + 517717 = 518000
397 + 517603 = 518000
487 + 517513 = 518000

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 518,000 and was likely granted around 1894.

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