Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495000, here are decompositions:

13 + 494987 = 495000
41 + 494959 = 495000
61 + 494939 = 495000
67 + 494933 = 495000
73 + 494927 = 495000
83 + 494917 = 495000
97 + 494903 = 495000
101 + 494899 = 495000

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 495,000 and was likely granted around 1893.

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