Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 170984, here are decompositions:
- 13 + 170971 = 170984
- 31 + 170953 = 170984
- 97 + 170887 = 170984
- 103 + 170881 = 170984
- 127 + 170857 = 170984
- 157 + 170827 = 170984
- 211 + 170773 = 170984
- 223 + 170761 = 170984
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 170,984 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 170984 first appears in π at position 28,826 of the decimal expansion (the 28,826ordinal-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.
