Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164426, here are decompositions:
- 7 + 164419 = 164426
- 13 + 164413 = 164426
- 127 + 164299 = 164426
- 193 + 164233 = 164426
- 277 + 164149 = 164426
- 313 + 164113 = 164426
- 337 + 164089 = 164426
- 433 + 163993 = 164426
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 164,426 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 164426 first appears in π at position 136,896 of the decimal expansion (the 136,896ordinal-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.
