Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671408, here are decompositions:
- 41 + 8671367 = 8671408
- 47 + 8671361 = 8671408
- 101 + 8671307 = 8671408
- 257 + 8671151 = 8671408
- 281 + 8671127 = 8671408
- 311 + 8671097 = 8671408
- 401 + 8671007 = 8671408
- 419 + 8670989 = 8671408
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 8,671,408 and was likely granted around 2014.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
