Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105958, here are decompositions:
- 5 + 105953 = 105958
- 29 + 105929 = 105958
- 59 + 105899 = 105958
- 191 + 105767 = 105958
- 197 + 105761 = 105958
- 257 + 105701 = 105958
- 401 + 105557 = 105958
- 431 + 105527 = 105958
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 105,958 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
