Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 170456, here are decompositions:
- 43 + 170413 = 170456
- 67 + 170389 = 170456
- 73 + 170383 = 170456
- 103 + 170353 = 170456
- 109 + 170347 = 170456
- 157 + 170299 = 170456
- 163 + 170293 = 170456
- 193 + 170263 = 170456
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 170,456 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 170456 first appears in π at position 858,930 of the decimal expansion (the 858,930ordinal-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.
