Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105554, here are decompositions:
- 13 + 105541 = 105554
- 37 + 105517 = 105554
- 157 + 105397 = 105554
- 181 + 105373 = 105554
- 193 + 105361 = 105554
- 223 + 105331 = 105554
- 277 + 105277 = 105554
- 457 + 105097 = 105554
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 105 554 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
