Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8684240, here are decompositions:
- 67 + 8684173 = 8684240
- 109 + 8684131 = 8684240
- 151 + 8684089 = 8684240
- 163 + 8684077 = 8684240
- 193 + 8684047 = 8684240
- 211 + 8684029 = 8684240
- 307 + 8683933 = 8684240
- 457 + 8683783 = 8684240
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 8,684,240 and was likely granted around 2014.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
This passes the ABA routing number checksum and matches the Federal Reserve numbering scheme.
Banks operate many routing numbers per state and division; an unmatched checksum-valid number can still be a real RTN at a smaller institution.
