Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 126164, here are decompositions:
- 13 + 126151 = 126164
- 37 + 126127 = 126164
- 67 + 126097 = 126164
- 97 + 126067 = 126164
- 127 + 126037 = 126164
- 151 + 126013 = 126164
- 163 + 126001 = 126164
- 223 + 125941 = 126164
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 126,164 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 126164 first appears in π at position 722,213 of the decimal expansion (the 722,213ordinal-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.
