Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164456, here are decompositions:
- 7 + 164449 = 164456
- 13 + 164443 = 164456
- 37 + 164419 = 164456
- 43 + 164413 = 164456
- 79 + 164377 = 164456
- 157 + 164299 = 164456
- 223 + 164233 = 164456
- 283 + 164173 = 164456
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 164,456 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 164456 first appears in π at position 61,594 of the decimal expansion (the 61,594ordinal-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.
