Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 170790, here are decompositions:
- 13 + 170777 = 170790
- 17 + 170773 = 170790
- 23 + 170767 = 170790
- 29 + 170761 = 170790
- 31 + 170759 = 170790
- 41 + 170749 = 170790
- 79 + 170711 = 170790
- 83 + 170707 = 170790
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 170,790 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 170790 first appears in π at position 77,423 of the decimal expansion (the 77,423ordinal-suffix:rd 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.
