Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687104, here are decompositions:
- 11 + 8687093 = 8687104
- 17 + 8687087 = 8687104
- 227 + 8686877 = 8687104
- 263 + 8686841 = 8687104
- 383 + 8686721 = 8687104
- 401 + 8686703 = 8687104
- 443 + 8686661 = 8687104
- 617 + 8686487 = 8687104
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 8,687,104 and was likely granted around 2014.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
