Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 131164, here are decompositions:
- 53 + 131111 = 131164
- 101 + 131063 = 131164
- 191 + 130973 = 131164
- 347 + 130817 = 131164
- 353 + 130811 = 131164
- 521 + 130643 = 131164
- 617 + 130547 = 131164
- 641 + 130523 = 131164
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 131,164 and was likely granted around 1872.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 131164 first appears in π at position 662,190 of the decimal expansion (the 662,190ordinal-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.
