Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164472, here are decompositions:
- 23 + 164449 = 164472
- 29 + 164443 = 164472
- 41 + 164431 = 164472
- 43 + 164429 = 164472
- 53 + 164419 = 164472
- 59 + 164413 = 164472
- 101 + 164371 = 164472
- 109 + 164363 = 164472
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 164,472 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 164472 first appears in π at position 300,828 of the decimal expansion (the 300,828ordinal-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.
