Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 170242, here are decompositions:
- 3 + 170239 = 170242
- 11 + 170231 = 170242
- 29 + 170213 = 170242
- 53 + 170189 = 170242
- 101 + 170141 = 170242
- 131 + 170111 = 170242
- 179 + 170063 = 170242
- 239 + 170003 = 170242
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 170,242 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 170242 first appears in π at position 676,519 of the decimal expansion (the 676,519ordinal-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.
