Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8684128, here are decompositions:
- 17 + 8684111 = 8684128
- 29 + 8684099 = 8684128
- 59 + 8684069 = 8684128
- 251 + 8683877 = 8684128
- 347 + 8683781 = 8684128
- 359 + 8683769 = 8684128
- 491 + 8683637 = 8684128
- 521 + 8683607 = 8684128
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 8,684,128 and was likely granted around 2014.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
