Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667820, here are decompositions:
- 11 + 8667809 = 8667820
- 23 + 8667797 = 8667820
- 113 + 8667707 = 8667820
- 131 + 8667689 = 8667820
- 167 + 8667653 = 8667820
- 179 + 8667641 = 8667820
- 257 + 8667563 = 8667820
- 281 + 8667539 = 8667820
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 8.667.820 and was likely granted around 2014.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
