Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680404, here are decompositions:
- 13 + 8680391 = 8680404
- 67 + 8680337 = 8680404
- 97 + 8680307 = 8680404
- 101 + 8680303 = 8680404
- 107 + 8680297 = 8680404
- 127 + 8680277 = 8680404
- 137 + 8680267 = 8680404
- 191 + 8680213 = 8680404
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 8 680 404 and was likely granted around 2014.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
