Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104398, here are decompositions:
- 5 + 104393 = 104398
- 17 + 104381 = 104398
- 29 + 104369 = 104398
- 71 + 104327 = 104398
- 89 + 104309 = 104398
- 101 + 104297 = 104398
- 167 + 104231 = 104398
- 191 + 104207 = 104398
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 104 398 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
