Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164372, here are decompositions:
- 31 + 164341 = 164372
- 73 + 164299 = 164372
- 139 + 164233 = 164372
- 163 + 164209 = 164372
- 181 + 164191 = 164372
- 199 + 164173 = 164372
- 223 + 164149 = 164372
- 283 + 164089 = 164372
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 164,372 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 164372 first appears in π at position 538,722 of the decimal expansion (the 538,722ordinal-suffix:nd 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.
