Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164866, here are decompositions:
- 29 + 164837 = 164866
- 137 + 164729 = 164866
- 239 + 164627 = 164866
- 353 + 164513 = 164866
- 389 + 164477 = 164866
- 419 + 164447 = 164866
- 479 + 164387 = 164866
- 503 + 164363 = 164866
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 164,866 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 164866 first appears in π at position 264,020 of the decimal expansion (the 264,020ordinal-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.
