Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166464, here are decompositions:
- 7 + 166457 = 166464
- 47 + 166417 = 166464
- 61 + 166403 = 166464
- 71 + 166393 = 166464
- 101 + 166363 = 166464
- 107 + 166357 = 166464
- 113 + 166351 = 166464
- 163 + 166301 = 166464
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 166,464 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 166464 first appears in π at position 404,949 of the decimal expansion (the 404,949ordinal-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.
