Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 492000, here are decompositions:

17 + 491983 = 492000
23 + 491977 = 492000
31 + 491969 = 492000
101 + 491899 = 492000
127 + 491873 = 492000
149 + 491851 = 492000
163 + 491837 = 492000
167 + 491833 = 492000

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 492,000 and was likely granted around 1893.

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