Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671284, here are decompositions:
- 53 + 8671231 = 8671284
- 107 + 8671177 = 8671284
- 137 + 8671147 = 8671284
- 151 + 8671133 = 8671284
- 157 + 8671127 = 8671284
- 227 + 8671057 = 8671284
- 233 + 8671051 = 8671284
- 277 + 8671007 = 8671284
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 8,671,284 and was likely granted around 2014.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
