Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105820, here are decompositions:
- 3 + 105817 = 105820
- 53 + 105767 = 105820
- 59 + 105761 = 105820
- 137 + 105683 = 105820
- 167 + 105653 = 105820
- 257 + 105563 = 105820
- 263 + 105557 = 105820
- 293 + 105527 = 105820
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 105.820 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
