Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 170042, here are decompositions:
- 13 + 170029 = 170042
- 109 + 169933 = 170042
- 151 + 169891 = 170042
- 199 + 169843 = 170042
- 211 + 169831 = 170042
- 349 + 169693 = 170042
- 409 + 169633 = 170042
- 541 + 169501 = 170042
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 170,042 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 170042 first appears in π at position 517,051 of the decimal expansion (the 517,051ordinal-suffix:st 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.
