Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105166, here are decompositions:
- 23 + 105143 = 105166
- 29 + 105137 = 105166
- 59 + 105107 = 105166
- 167 + 104999 = 105166
- 179 + 104987 = 105166
- 233 + 104933 = 105166
- 317 + 104849 = 105166
- 443 + 104723 = 105166
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 105,166 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 105166 first appears in π at position 855,387 of the decimal expansion (the 855,387ordinal-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.
