Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1000458, here are decompositions:

5 + 1000453 = 1000458
29 + 1000429 = 1000458
31 + 1000427 = 1000458
61 + 1000397 = 1000458
101 + 1000357 = 1000458
167 + 1000291 = 1000458
227 + 1000231 = 1000458
271 + 1000187 = 1000458

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 1,000,458 and was likely granted around 1911.

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