Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171584, here are decompositions:
- 13 + 171571 = 171584
- 31 + 171553 = 171584
- 43 + 171541 = 171584
- 67 + 171517 = 171584
- 103 + 171481 = 171584
- 157 + 171427 = 171584
- 181 + 171403 = 171584
- 313 + 171271 = 171584
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 171,584 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 171584 first appears in π at position 432,800 of the decimal expansion (the 432,800ordinal-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.
