Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 149164, here are decompositions:
- 3 + 149161 = 149164
- 5 + 149159 = 149164
- 11 + 149153 = 149164
- 53 + 149111 = 149164
- 107 + 149057 = 149164
- 131 + 149033 = 149164
- 137 + 149027 = 149164
- 167 + 148997 = 149164
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 149,164 and was likely granted around 1873.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 149164 first appears in π at position 703,333 of the decimal expansion (the 703,333ordinal-suffix:rd 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.
