Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8664744, here are decompositions:
- 5 + 8664739 = 8664744
- 13 + 8664731 = 8664744
- 43 + 8664701 = 8664744
- 73 + 8664671 = 8664744
- 83 + 8664661 = 8664744
- 131 + 8664613 = 8664744
- 163 + 8664581 = 8664744
- 191 + 8664553 = 8664744
Showing the first eight; more decompositions exist.
As an unsigned 32-bit integer, this is the IPv4 address 0.132.54.168.

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 8,664,744 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 8664744 first appears in π at position 842,307 of the decimal expansion (the 842,307ordinal-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.
