Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105556, here are decompositions:
- 23 + 105533 = 105556
- 29 + 105527 = 105556
- 47 + 105509 = 105556
- 53 + 105503 = 105556
- 89 + 105467 = 105556
- 107 + 105449 = 105556
- 149 + 105407 = 105556
- 167 + 105389 = 105556
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 105 556 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
