Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 170884, here are decompositions:
- 3 + 170881 = 170884
- 11 + 170873 = 170884
- 41 + 170843 = 170884
- 47 + 170837 = 170884
- 71 + 170813 = 170884
- 83 + 170801 = 170884
- 107 + 170777 = 170884
- 173 + 170711 = 170884
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 170,884 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 170884 first appears in π at position 820,614 of the decimal expansion (the 820,614ordinal-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.
