Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8664940, here are decompositions:
- 71 + 8664869 = 8664940
- 83 + 8664857 = 8664940
- 149 + 8664791 = 8664940
- 197 + 8664743 = 8664940
- 239 + 8664701 = 8664940
- 269 + 8664671 = 8664940
- 359 + 8664581 = 8664940
- 467 + 8664473 = 8664940
Showing the first eight; more decompositions exist.

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 8,664,940 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 8664940 first appears in π at position 89,143 of the decimal expansion (the 89,143ordinal-suffix:rd 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.
