Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164664, here are decompositions:
- 11 + 164653 = 164664
- 37 + 164627 = 164664
- 41 + 164623 = 164664
- 43 + 164621 = 164664
- 47 + 164617 = 164664
- 83 + 164581 = 164664
- 151 + 164513 = 164664
- 193 + 164471 = 164664
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 164,664 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 164664 first appears in π at position 360,115 of the decimal expansion (the 360,115ordinal-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.
