Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687724, here are decompositions:
- 11 + 8687713 = 8687724
- 37 + 8687687 = 8687724
- 53 + 8687671 = 8687724
- 83 + 8687641 = 8687724
- 137 + 8687587 = 8687724
- 211 + 8687513 = 8687724
- 257 + 8687467 = 8687724
- 263 + 8687461 = 8687724
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 8,687,724 and was likely granted around 2014.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
