Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8664000, here are decompositions:
- 13 + 8663987 = 8664000
- 31 + 8663969 = 8664000
- 41 + 8663959 = 8664000
- 101 + 8663899 = 8664000
- 131 + 8663869 = 8664000
- 139 + 8663861 = 8664000
- 173 + 8663827 = 8664000
- 179 + 8663821 = 8664000
Showing the first eight; more decompositions exist.
As an unsigned 32-bit integer, this is the IPv4 address 0.132.51.192.

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 8,664,000 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 8664000 first appears in π at position 933,014 of the decimal expansion (the 933,014ordinal-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.
