Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105712, here are decompositions:
- 11 + 105701 = 105712
- 29 + 105683 = 105712
- 59 + 105653 = 105712
- 149 + 105563 = 105712
- 179 + 105533 = 105712
- 263 + 105449 = 105712
- 311 + 105401 = 105712
- 353 + 105359 = 105712
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 105 712 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
