Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687164, here are decompositions:
- 23 + 8687141 = 8687164
- 47 + 8687117 = 8687164
- 71 + 8687093 = 8687164
- 137 + 8687027 = 8687164
- 263 + 8686901 = 8687164
- 281 + 8686883 = 8687164
- 443 + 8686721 = 8687164
- 461 + 8686703 = 8687164
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 8,687,164 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 8687164 first appears in π at position 122,345 of the decimal expansion (the 122,345ordinal-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.
