Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490430, here are decompositions:

13 + 490417 = 490430
37 + 490393 = 490430
163 + 490267 = 490430
181 + 490249 = 490430
223 + 490207 = 490430
229 + 490201 = 490430
271 + 490159 = 490430
313 + 490117 = 490430

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 490,430 and was likely granted around 1892.

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