Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164788, here are decompositions:
- 17 + 164771 = 164788
- 59 + 164729 = 164788
- 167 + 164621 = 164788
- 257 + 164531 = 164788
- 311 + 164477 = 164788
- 317 + 164471 = 164788
- 359 + 164429 = 164788
- 401 + 164387 = 164788
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 164,788 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 164788 first appears in π at position 748,557 of the decimal expansion (the 748,557ordinal-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.
