Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165466, here are decompositions:
- 3 + 165463 = 165466
- 17 + 165449 = 165466
- 23 + 165443 = 165466
- 29 + 165437 = 165466
- 83 + 165383 = 165466
- 149 + 165317 = 165466
- 173 + 165293 = 165466
- 179 + 165287 = 165466
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 165,466 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 165466 first appears in π at position 523,789 of the decimal expansion (the 523,789ordinal-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.
