Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100458, here are decompositions:
- 11 + 100447 = 100458
- 41 + 100417 = 100458
- 47 + 100411 = 100458
- 67 + 100391 = 100458
- 79 + 100379 = 100458
- 97 + 100361 = 100458
- 101 + 100357 = 100458
- 167 + 100291 = 100458
Showing the first eight; more decompositions exist.

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 100,458 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
