Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164406, here are decompositions:
- 19 + 164387 = 164406
- 29 + 164377 = 164406
- 43 + 164363 = 164406
- 97 + 164309 = 164406
- 107 + 164299 = 164406
- 127 + 164279 = 164406
- 139 + 164267 = 164406
- 157 + 164249 = 164406
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 164,406 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 164406 first appears in π at position 725,356 of the decimal expansion (the 725,356ordinal-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.
