Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166960, here are decompositions:
- 11 + 166949 = 166960
- 29 + 166931 = 166960
- 41 + 166919 = 166960
- 89 + 166871 = 166960
- 107 + 166853 = 166960
- 113 + 166847 = 166960
- 137 + 166823 = 166960
- 179 + 166781 = 166960
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 166,960 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 166960 first appears in π at position 405,018 of the decimal expansion (the 405,018ordinal-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.
