Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105436, here are decompositions:
- 29 + 105407 = 105436
- 47 + 105389 = 105436
- 113 + 105323 = 105436
- 167 + 105269 = 105436
- 173 + 105263 = 105436
- 197 + 105239 = 105436
- 263 + 105173 = 105436
- 269 + 105167 = 105436
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 105,436 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
