Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490354, here are decompositions:

41 + 490313 = 490354
71 + 490283 = 490354
83 + 490271 = 490354
107 + 490247 = 490354
113 + 490241 = 490354
131 + 490223 = 490354
233 + 490121 = 490354
251 + 490103 = 490354

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 490,354 and was likely granted around 1892.

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