Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105560, here are decompositions:
- 3 + 105557 = 105560
- 19 + 105541 = 105560
- 31 + 105529 = 105560
- 43 + 105517 = 105560
- 61 + 105499 = 105560
- 163 + 105397 = 105560
- 181 + 105379 = 105560
- 193 + 105367 = 105560
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 105,560 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
