Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105580, here are decompositions:
- 17 + 105563 = 105580
- 23 + 105557 = 105580
- 47 + 105533 = 105580
- 53 + 105527 = 105580
- 71 + 105509 = 105580
- 89 + 105491 = 105580
- 113 + 105467 = 105580
- 131 + 105449 = 105580
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 105.580 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
