Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105432, here are decompositions:
- 31 + 105401 = 105432
- 43 + 105389 = 105432
- 53 + 105379 = 105432
- 59 + 105373 = 105432
- 71 + 105361 = 105432
- 73 + 105359 = 105432
- 101 + 105331 = 105432
- 109 + 105323 = 105432
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 105 432 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
