Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687624, here are decompositions:
- 37 + 8687587 = 8687624
- 103 + 8687521 = 8687624
- 157 + 8687467 = 8687624
- 163 + 8687461 = 8687624
- 223 + 8687401 = 8687624
- 241 + 8687383 = 8687624
- 307 + 8687317 = 8687624
- 397 + 8687227 = 8687624
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 8,687,624 and was likely granted around 2014.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
