Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164404, here are decompositions:
- 17 + 164387 = 164404
- 41 + 164363 = 164404
- 47 + 164357 = 164404
- 83 + 164321 = 164404
- 113 + 164291 = 164404
- 137 + 164267 = 164404
- 173 + 164231 = 164404
- 257 + 164147 = 164404
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 164,404 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 164404 first appears in π at position 535,364 of the decimal expansion (the 535,364ordinal-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.
