Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164424, here are decompositions:
- 5 + 164419 = 164424
- 11 + 164413 = 164424
- 37 + 164387 = 164424
- 47 + 164377 = 164424
- 53 + 164371 = 164424
- 61 + 164363 = 164424
- 67 + 164357 = 164424
- 83 + 164341 = 164424
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 164,424 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 164424 first appears in π at position 480,096 of the decimal expansion (the 480,096ordinal-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.
