Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687424, here are decompositions:
- 23 + 8687401 = 8687424
- 37 + 8687387 = 8687424
- 41 + 8687383 = 8687424
- 43 + 8687381 = 8687424
- 61 + 8687363 = 8687424
- 103 + 8687321 = 8687424
- 107 + 8687317 = 8687424
- 191 + 8687233 = 8687424
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 8,687,424 and was likely granted around 2014.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
