Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105452, here are decompositions:
- 3 + 105449 = 105452
- 73 + 105379 = 105452
- 79 + 105373 = 105452
- 199 + 105253 = 105452
- 223 + 105229 = 105452
- 241 + 105211 = 105452
- 421 + 105031 = 105452
- 433 + 105019 = 105452
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 105 452 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
