Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687008, here are decompositions:
- 47 + 8686961 = 8687008
- 107 + 8686901 = 8687008
- 131 + 8686877 = 8687008
- 167 + 8686841 = 8687008
- 179 + 8686829 = 8687008
- 347 + 8686661 = 8687008
- 419 + 8686589 = 8687008
- 479 + 8686529 = 8687008
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 8,687,008 and was likely granted around 2014.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
