Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515510, here are decompositions:

3 + 515507 = 515510
109 + 515401 = 515510
139 + 515371 = 515510
199 + 515311 = 515510
277 + 515233 = 515510
283 + 515227 = 515510
337 + 515173 = 515510
367 + 515143 = 515510

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 515,510 and was likely granted around 1894.

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