Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166160, here are decompositions:
- 3 + 166157 = 166160
- 13 + 166147 = 166160
- 61 + 166099 = 166160
- 79 + 166081 = 166160
- 97 + 166063 = 166160
- 139 + 166021 = 166160
- 199 + 165961 = 166160
- 229 + 165931 = 166160
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 166,160 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 166160 first appears in π at position 587,639 of the decimal expansion (the 587,639ordinal-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.
