Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8684420, here are decompositions:
- 13 + 8684407 = 8684420
- 61 + 8684359 = 8684420
- 79 + 8684341 = 8684420
- 163 + 8684257 = 8684420
- 313 + 8684107 = 8684420
- 331 + 8684089 = 8684420
- 373 + 8684047 = 8684420
- 397 + 8684023 = 8684420
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 8,684,420 and was likely granted around 2014.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
