Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166750, here are decompositions:
- 11 + 166739 = 166750
- 47 + 166703 = 166750
- 71 + 166679 = 166750
- 83 + 166667 = 166750
- 107 + 166643 = 166750
- 131 + 166619 = 166750
- 137 + 166613 = 166750
- 149 + 166601 = 166750
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 166,750 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 166750 first appears in π at position 270,027 of the decimal expansion (the 270,027ordinal-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.
