Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171164, here are decompositions:
- 3 + 171161 = 171164
- 61 + 171103 = 171164
- 73 + 171091 = 171164
- 157 + 171007 = 171164
- 193 + 170971 = 171164
- 211 + 170953 = 171164
- 277 + 170887 = 171164
- 283 + 170881 = 171164
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 171,164 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 171164 first appears in π at position 300,825 of the decimal expansion (the 300,825ordinal-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.
