Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171120, here are decompositions:
- 17 + 171103 = 171120
- 29 + 171091 = 171120
- 41 + 171079 = 171120
- 43 + 171077 = 171120
- 67 + 171053 = 171120
- 71 + 171049 = 171120
- 73 + 171047 = 171120
- 97 + 171023 = 171120
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 171,120 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 171120 first appears in π at position 163,699 of the decimal expansion (the 163,699ordinal-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.
