Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104390, here are decompositions:
- 7 + 104383 = 104390
- 43 + 104347 = 104390
- 67 + 104323 = 104390
- 79 + 104311 = 104390
- 103 + 104287 = 104390
- 109 + 104281 = 104390
- 151 + 104239 = 104390
- 157 + 104233 = 104390
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 104 390 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
