Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102408, here are decompositions:
- 11 + 102397 = 102408
- 41 + 102367 = 102408
- 71 + 102337 = 102408
- 79 + 102329 = 102408
- 107 + 102301 = 102408
- 109 + 102299 = 102408
- 149 + 102259 = 102408
- 157 + 102251 = 102408
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 102,408 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
