Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 170656, here are decompositions:
- 23 + 170633 = 170656
- 29 + 170627 = 170656
- 47 + 170609 = 170656
- 53 + 170603 = 170656
- 173 + 170483 = 170656
- 263 + 170393 = 170656
- 293 + 170363 = 170656
- 389 + 170267 = 170656
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 170,656 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 170656 first appears in π at position 229,399 of the decimal expansion (the 229,399ordinal-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.
