Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166342, here are decompositions:
- 23 + 166319 = 166342
- 41 + 166301 = 166342
- 53 + 166289 = 166342
- 83 + 166259 = 166342
- 173 + 166169 = 166342
- 191 + 166151 = 166342
- 311 + 166031 = 166342
- 359 + 165983 = 166342
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 166,342 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 166342 first appears in π at position 804,180 of the decimal expansion (the 804,180ordinal-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.
