Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 175408, here are decompositions:
- 5 + 175403 = 175408
- 17 + 175391 = 175408
- 47 + 175361 = 175408
- 59 + 175349 = 175408
- 131 + 175277 = 175408
- 179 + 175229 = 175408
- 197 + 175211 = 175408
- 347 + 175061 = 175408
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 175,408 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 175408 first appears in π at position 204,660 of the decimal expansion (the 204,660ordinal-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.
