Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 173166, here are decompositions:
- 17 + 173149 = 173166
- 29 + 173137 = 173166
- 67 + 173099 = 173166
- 79 + 173087 = 173166
- 107 + 173059 = 173166
- 113 + 173053 = 173166
- 127 + 173039 = 173166
- 167 + 172999 = 173166
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 173,166 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 173166 first appears in π at position 859,173 of the decimal expansion (the 859,173ordinal-suffix:rd 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.
