Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666604, here are decompositions:
- 7 + 8666597 = 8666604
- 13 + 8666591 = 8666604
- 61 + 8666543 = 8666604
- 71 + 8666533 = 8666604
- 103 + 8666501 = 8666604
- 113 + 8666491 = 8666604
- 127 + 8666477 = 8666604
- 173 + 8666431 = 8666604
Showing the first eight; more decompositions exist.
As an unsigned 32-bit integer, this is the IPv4 address 0.132.61.236.

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 8,666,604 and was likely granted around 2014.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 8666604 first appears in π at position 516,071 of the decimal expansion (the 516,071ordinal-suffix:st digit after the integer 3).
Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
