Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511600, here are decompositions:

17 + 511583 = 511600
41 + 511559 = 511600
59 + 511541 = 511600
113 + 511487 = 511600
137 + 511463 = 511600
191 + 511409 = 511600
239 + 511361 = 511600
263 + 511337 = 511600

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 511,600 and was likely granted around 1893.

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