Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100258, here are decompositions:
- 89 + 100169 = 100258
- 107 + 100151 = 100258
- 149 + 100109 = 100258
- 239 + 100019 = 100258
- 269 + 99989 = 100258
- 419 + 99839 = 100258
- 449 + 99809 = 100258
- 491 + 99767 = 100258
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 100,258 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
