Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687340, here are decompositions:
- 19 + 8687321 = 8687340
- 23 + 8687317 = 8687340
- 31 + 8687309 = 8687340
- 37 + 8687303 = 8687340
- 41 + 8687299 = 8687340
- 107 + 8687233 = 8687340
- 113 + 8687227 = 8687340
- 127 + 8687213 = 8687340
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 8,687,340 and was likely granted around 2014.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
