Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164868, here are decompositions:
- 29 + 164839 = 164868
- 31 + 164837 = 164868
- 37 + 164831 = 164868
- 47 + 164821 = 164868
- 59 + 164809 = 164868
- 79 + 164789 = 164868
- 97 + 164771 = 164868
- 101 + 164767 = 164868
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 164,868 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 164868 first appears in π at position 111,579 of the decimal expansion (the 111,579ordinal-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.
