Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 510500, here are decompositions:

19 + 510481 = 510500
37 + 510463 = 510500
43 + 510457 = 510500
97 + 510403 = 510500
139 + 510361 = 510500
181 + 510319 = 510500
229 + 510271 = 510500
283 + 510217 = 510500

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 510,500 and was likely granted around 1893.

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