Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164238, here are decompositions:
- 5 + 164233 = 164238
- 7 + 164231 = 164238
- 29 + 164209 = 164238
- 37 + 164201 = 164238
- 47 + 164191 = 164238
- 89 + 164149 = 164238
- 149 + 164089 = 164238
- 167 + 164071 = 164238
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 164,238 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 164238 first appears in π at position 869,117 of the decimal expansion (the 869,117ordinal-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.
