Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 170390, here are decompositions:
- 7 + 170383 = 170390
- 19 + 170371 = 170390
- 37 + 170353 = 170390
- 43 + 170347 = 170390
- 97 + 170293 = 170390
- 127 + 170263 = 170390
- 151 + 170239 = 170390
- 163 + 170227 = 170390
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 170,390 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 170390 first appears in π at position 21,673 of the decimal expansion (the 21,673ordinal-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.
