Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 106666, here are decompositions:
- 3 + 106663 = 106666
- 5 + 106661 = 106666
- 17 + 106649 = 106666
- 29 + 106637 = 106666
- 47 + 106619 = 106666
- 179 + 106487 = 106666
- 233 + 106433 = 106666
- 239 + 106427 = 106666
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 106,666 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 106666 first appears in π at position 124,492 of the decimal expansion (the 124,492ordinal-suffix:nd 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.
