Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103904, here are decompositions:
- 37 + 103867 = 103904
- 61 + 103843 = 103904
- 67 + 103837 = 103904
- 103 + 103801 = 103904
- 181 + 103723 = 103904
- 223 + 103681 = 103904
- 313 + 103591 = 103904
- 331 + 103573 = 103904
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 103 904 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
