Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166958, here are decompositions:
- 97 + 166861 = 166958
- 109 + 166849 = 166958
- 151 + 166807 = 166958
- 331 + 166627 = 166958
- 349 + 166609 = 166958
- 397 + 166561 = 166958
- 487 + 166471 = 166958
- 541 + 166417 = 166958
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 166,958 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 166958 first appears in π at position 589,710 of the decimal expansion (the 589,710ordinal-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.
