Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 168164, here are decompositions:
- 13 + 168151 = 168164
- 37 + 168127 = 168164
- 97 + 168067 = 168164
- 127 + 168037 = 168164
- 151 + 168013 = 168164
- 193 + 167971 = 168164
- 211 + 167953 = 168164
- 277 + 167887 = 168164
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 168,164 and was likely granted around 1874.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 168164 first appears in π at position 75,766 of the decimal expansion (the 75,766ordinal-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.
