Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172464, here are decompositions:
- 23 + 172441 = 172464
- 31 + 172433 = 172464
- 37 + 172427 = 172464
- 41 + 172423 = 172464
- 43 + 172421 = 172464
- 53 + 172411 = 172464
- 107 + 172357 = 172464
- 113 + 172351 = 172464
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 172,464 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 172464 first appears in π at position 46,611 of the decimal expansion (the 46,611ordinal-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.
