Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 493000, here are decompositions:

89 + 492911 = 493000
107 + 492893 = 493000
239 + 492761 = 493000
269 + 492731 = 493000
281 + 492719 = 493000
293 + 492707 = 493000
353 + 492647 = 493000
359 + 492641 = 493000

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 493,000 and was likely granted around 1893.

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