Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166424, here are decompositions:
- 7 + 166417 = 166424
- 31 + 166393 = 166424
- 61 + 166363 = 166424
- 67 + 166357 = 166424
- 73 + 166351 = 166424
- 127 + 166297 = 166424
- 151 + 166273 = 166424
- 241 + 166183 = 166424
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 166,424 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 166424 first appears in π at position 472,694 of the decimal expansion (the 472,694ordinal-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.
