Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105724, here are decompositions:
- 23 + 105701 = 105724
- 41 + 105683 = 105724
- 71 + 105653 = 105724
- 167 + 105557 = 105724
- 191 + 105533 = 105724
- 197 + 105527 = 105724
- 233 + 105491 = 105724
- 257 + 105467 = 105724
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 105.724 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
