Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8679820, here are decompositions:
- 29 + 8679791 = 8679820
- 53 + 8679767 = 8679820
- 179 + 8679641 = 8679820
- 239 + 8679581 = 8679820
- 263 + 8679557 = 8679820
- 269 + 8679551 = 8679820
- 293 + 8679527 = 8679820
- 467 + 8679353 = 8679820
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 8,679,820 and was likely granted around 2014.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
