Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105146, here are decompositions:
- 3 + 105143 = 105146
- 109 + 105037 = 105146
- 127 + 105019 = 105146
- 193 + 104953 = 105146
- 199 + 104947 = 105146
- 229 + 104917 = 105146
- 277 + 104869 = 105146
- 367 + 104779 = 105146
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 105 146 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
