Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105424, here are decompositions:
- 17 + 105407 = 105424
- 23 + 105401 = 105424
- 83 + 105341 = 105424
- 101 + 105323 = 105424
- 173 + 105251 = 105424
- 197 + 105227 = 105424
- 251 + 105173 = 105424
- 257 + 105167 = 105424
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 105,424 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
