Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509404, here are decompositions:
- 11 + 509393 = 509404
- 41 + 509363 = 509404
- 107 + 509297 = 509404
- 257 + 509147 = 509404
- 281 + 509123 = 509404
- 317 + 509087 = 509404
- 431 + 508973 = 509404
- 443 + 508961 = 509404
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 509,404 and was likely granted around 1893.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
