Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164722, here are decompositions:
- 59 + 164663 = 164722
- 101 + 164621 = 164722
- 191 + 164531 = 164722
- 251 + 164471 = 164722
- 293 + 164429 = 164722
- 359 + 164363 = 164722
- 401 + 164321 = 164722
- 431 + 164291 = 164722
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 164,722 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 164722 first appears in π at position 134,749 of the decimal expansion (the 134,749ordinal-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.
