Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104808, here are decompositions:
- 5 + 104803 = 104808
- 7 + 104801 = 104808
- 19 + 104789 = 104808
- 29 + 104779 = 104808
- 47 + 104761 = 104808
- 79 + 104729 = 104808
- 97 + 104711 = 104808
- 101 + 104707 = 104808
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 104 808 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
