Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103808, here are decompositions:
- 7 + 103801 = 103808
- 109 + 103699 = 103808
- 127 + 103681 = 103808
- 139 + 103669 = 103808
- 151 + 103657 = 103808
- 157 + 103651 = 103808
- 241 + 103567 = 103808
- 337 + 103471 = 103808
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 103,808 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
