Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8684820, here are decompositions:
- 31 + 8684789 = 8684820
- 37 + 8684783 = 8684820
- 59 + 8684761 = 8684820
- 61 + 8684759 = 8684820
- 73 + 8684747 = 8684820
- 107 + 8684713 = 8684820
- 127 + 8684693 = 8684820
- 163 + 8684657 = 8684820
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 8,684,820 and was likely granted around 2014.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
