Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 499000, here are decompositions:

11 + 498989 = 499000
23 + 498977 = 499000
53 + 498947 = 499000
167 + 498833 = 499000
197 + 498803 = 499000
233 + 498767 = 499000
239 + 498761 = 499000
251 + 498749 = 499000

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 499,000 and was likely granted around 1893.

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