Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511900, here are decompositions:

3 + 511897 = 511900
41 + 511859 = 511900
89 + 511811 = 511900
107 + 511793 = 511900
113 + 511787 = 511900
197 + 511703 = 511900
269 + 511631 = 511900
317 + 511583 = 511900

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 511,900 and was likely granted around 1893.

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