Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100408, here are decompositions:
- 5 + 100403 = 100408
- 17 + 100391 = 100408
- 29 + 100379 = 100408
- 47 + 100361 = 100408
- 137 + 100271 = 100408
- 239 + 100169 = 100408
- 257 + 100151 = 100408
- 359 + 100049 = 100408
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 100,408 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
