Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8684720, here are decompositions:
- 7 + 8684713 = 8684720
- 199 + 8684521 = 8684720
- 241 + 8684479 = 8684720
- 283 + 8684437 = 8684720
- 313 + 8684407 = 8684720
- 379 + 8684341 = 8684720
- 463 + 8684257 = 8684720
- 547 + 8684173 = 8684720
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 8,684,720 and was likely granted around 2014.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
