Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166242, here are decompositions:
- 5 + 166237 = 166242
- 23 + 166219 = 166242
- 53 + 166189 = 166242
- 59 + 166183 = 166242
- 73 + 166169 = 166242
- 179 + 166063 = 166242
- 199 + 166043 = 166242
- 211 + 166031 = 166242
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 166,242 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 166242 first appears in π at position 655,972 of the decimal expansion (the 655,972ordinal-suffix:nd 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.
