Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509500, here are decompositions:

23 + 509477 = 509500
59 + 509441 = 509500
71 + 509429 = 509500
83 + 509417 = 509500
107 + 509393 = 509500
137 + 509363 = 509500
353 + 509147 = 509500
557 + 508943 = 509500

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 509,500 and was likely granted around 1893.

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