Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171248, here are decompositions:
- 79 + 171169 = 171248
- 157 + 171091 = 171248
- 199 + 171049 = 171248
- 241 + 171007 = 171248
- 277 + 170971 = 171248
- 349 + 170899 = 171248
- 367 + 170881 = 171248
- 397 + 170851 = 171248
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 171,248 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 171248 first appears in π at position 243,585 of the decimal expansion (the 243,585ordinal-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.
