Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105308, here are decompositions:
- 31 + 105277 = 105308
- 79 + 105229 = 105308
- 97 + 105211 = 105308
- 109 + 105199 = 105308
- 211 + 105097 = 105308
- 271 + 105037 = 105308
- 277 + 105031 = 105308
- 337 + 104971 = 105308
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 105 308 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
