Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 500686, here are decompositions:

83 + 500603 = 500686
107 + 500579 = 500686
167 + 500519 = 500686
227 + 500459 = 500686
269 + 500417 = 500686
293 + 500393 = 500686
317 + 500369 = 500686
353 + 500333 = 500686

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 500,686 and was likely granted around 1893.

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