Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105448, here are decompositions:
- 11 + 105437 = 105448
- 41 + 105407 = 105448
- 47 + 105401 = 105448
- 59 + 105389 = 105448
- 89 + 105359 = 105448
- 107 + 105341 = 105448
- 179 + 105269 = 105448
- 197 + 105251 = 105448
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 105 448 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
