Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102308, here are decompositions:
- 7 + 102301 = 102308
- 67 + 102241 = 102308
- 79 + 102229 = 102308
- 109 + 102199 = 102308
- 127 + 102181 = 102308
- 229 + 102079 = 102308
- 277 + 102031 = 102308
- 307 + 102001 = 102308
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 102,308 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
