Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501458, here are decompositions:

7 + 501451 = 501458
31 + 501427 = 501458
229 + 501229 = 501458
241 + 501217 = 501458
271 + 501187 = 501458
337 + 501121 = 501458
421 + 501037 = 501458
439 + 501019 = 501458

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 501,458 and was likely granted around 1893.

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