Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171624, here are decompositions:
- 7 + 171617 = 171624
- 41 + 171583 = 171624
- 53 + 171571 = 171624
- 71 + 171553 = 171624
- 83 + 171541 = 171624
- 107 + 171517 = 171624
- 151 + 171473 = 171624
- 157 + 171467 = 171624
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 171,624 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 171624 first appears in π at position 279,269 of the decimal expansion (the 279,269ordinal-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.
