Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671166, here are decompositions:
- 19 + 8671147 = 8671166
- 67 + 8671099 = 8671166
- 103 + 8671063 = 8671166
- 109 + 8671057 = 8671166
- 157 + 8671009 = 8671166
- 223 + 8670943 = 8671166
- 457 + 8670709 = 8671166
- 463 + 8670703 = 8671166
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 8,671,166 and was likely granted around 2014.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
