Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164008, here are decompositions:
- 11 + 163997 = 164008
- 17 + 163991 = 164008
- 29 + 163979 = 164008
- 107 + 163901 = 164008
- 137 + 163871 = 164008
- 149 + 163859 = 164008
- 167 + 163841 = 164008
- 197 + 163811 = 164008
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 164,008 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 164008 first appears in π at position 183,791 of the decimal expansion (the 183,791ordinal-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.
