Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105660, here are decompositions:
- 7 + 105653 = 105660
- 11 + 105649 = 105660
- 41 + 105619 = 105660
- 47 + 105613 = 105660
- 53 + 105607 = 105660
- 59 + 105601 = 105660
- 97 + 105563 = 105660
- 103 + 105557 = 105660
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 105 660 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
