Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105658, here are decompositions:
- 5 + 105653 = 105658
- 101 + 105557 = 105658
- 131 + 105527 = 105658
- 149 + 105509 = 105658
- 167 + 105491 = 105658
- 191 + 105467 = 105658
- 251 + 105407 = 105658
- 257 + 105401 = 105658
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 105,658 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
