Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 170660, here are decompositions:
- 13 + 170647 = 170660
- 19 + 170641 = 170660
- 103 + 170557 = 170660
- 109 + 170551 = 170660
- 151 + 170509 = 170660
- 157 + 170503 = 170660
- 163 + 170497 = 170660
- 271 + 170389 = 170660
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 170,660 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 170660 first appears in π at position 533,412 of the decimal expansion (the 533,412ordinal-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.
