Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105422, here are decompositions:
- 43 + 105379 = 105422
- 61 + 105361 = 105422
- 103 + 105319 = 105422
- 193 + 105229 = 105422
- 211 + 105211 = 105422
- 223 + 105199 = 105422
- 463 + 104959 = 105422
- 571 + 104851 = 105422
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 105 422 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
