Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104420, here are decompositions:
- 3 + 104417 = 104420
- 37 + 104383 = 104420
- 73 + 104347 = 104420
- 97 + 104323 = 104420
- 109 + 104311 = 104420
- 139 + 104281 = 104420
- 181 + 104239 = 104420
- 241 + 104179 = 104420
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 104,420 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
