Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 170642, here are decompositions:
- 103 + 170539 = 170642
- 139 + 170503 = 170642
- 229 + 170413 = 170642
- 271 + 170371 = 170642
- 349 + 170293 = 170642
- 379 + 170263 = 170642
- 463 + 170179 = 170642
- 541 + 170101 = 170642
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 170,642 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 170642 first appears in π at position 741,597 of the decimal expansion (the 741,597ordinal-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.
