Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164268, here are decompositions:
- 17 + 164251 = 164268
- 19 + 164249 = 164268
- 29 + 164239 = 164268
- 37 + 164231 = 164268
- 59 + 164209 = 164268
- 67 + 164201 = 164268
- 151 + 164117 = 164268
- 179 + 164089 = 164268
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 164,268 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 164268 first appears in π at position 489,991 of the decimal expansion (the 489,991ordinal-suffix:st 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.
