Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105860, here are decompositions:
- 31 + 105829 = 105860
- 43 + 105817 = 105860
- 109 + 105751 = 105860
- 127 + 105733 = 105860
- 193 + 105667 = 105860
- 211 + 105649 = 105860
- 241 + 105619 = 105860
- 331 + 105529 = 105860
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 105,860 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
