Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 136666, here are decompositions:
- 17 + 136649 = 136666
- 59 + 136607 = 136666
- 107 + 136559 = 136666
- 263 + 136403 = 136666
- 269 + 136397 = 136666
- 293 + 136373 = 136666
- 347 + 136319 = 136666
- 389 + 136277 = 136666
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 136,666 and was likely granted around 1872.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 136666 first appears in π at position 180,720 of the decimal expansion (the 180,720ordinal-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.
