Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 170408, here are decompositions:
- 19 + 170389 = 170408
- 37 + 170371 = 170408
- 61 + 170347 = 170408
- 67 + 170341 = 170408
- 109 + 170299 = 170408
- 181 + 170227 = 170408
- 211 + 170197 = 170408
- 229 + 170179 = 170408
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 170,408 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 170408 first appears in π at position 733,579 of the decimal expansion (the 733,579ordinal-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.
