Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8664560, here are decompositions:
- 7 + 8664553 = 8664560
- 13 + 8664547 = 8664560
- 31 + 8664529 = 8664560
- 43 + 8664517 = 8664560
- 109 + 8664451 = 8664560
- 127 + 8664433 = 8664560
- 139 + 8664421 = 8664560
- 193 + 8664367 = 8664560
Showing the first eight; more decompositions exist.
As an unsigned 32-bit integer, this is the IPv4 address 0.132.53.240.

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 8,664,560 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 8664560 first appears in π at position 277,437 of the decimal expansion (the 277,437ordinal-suffix:th 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.
