Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667284, here are decompositions:
- 13 + 8667271 = 8667284
- 163 + 8667121 = 8667284
- 181 + 8667103 = 8667284
- 331 + 8666953 = 8667284
- 421 + 8666863 = 8667284
- 487 + 8666797 = 8667284
- 601 + 8666683 = 8667284
- 751 + 8666533 = 8667284
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 8,667,284 and was likely granted around 2014.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
