Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666566, here are decompositions:
- 23 + 8666543 = 8666566
- 47 + 8666519 = 8666566
- 53 + 8666513 = 8666566
- 89 + 8666477 = 8666566
- 107 + 8666459 = 8666566
- 149 + 8666417 = 8666566
- 173 + 8666393 = 8666566
- 179 + 8666387 = 8666566
Showing the first eight; more decompositions exist.
As an unsigned 32-bit integer, this is the IPv4 address 0.132.61.198.

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 8,666,566 and was likely granted around 2014.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
