Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105506, here are decompositions:
- 3 + 105503 = 105506
- 7 + 105499 = 105506
- 109 + 105397 = 105506
- 127 + 105379 = 105506
- 139 + 105367 = 105506
- 229 + 105277 = 105506
- 277 + 105229 = 105506
- 307 + 105199 = 105506
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 105,506 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
