Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164208, here are decompositions:
- 7 + 164201 = 164208
- 17 + 164191 = 164208
- 59 + 164149 = 164208
- 61 + 164147 = 164208
- 137 + 164071 = 164208
- 151 + 164057 = 164208
- 157 + 164051 = 164208
- 197 + 164011 = 164208
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 164,208 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 164208 first appears in π at position 897,566 of the decimal expansion (the 897,566ordinal-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.
