Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 173242, here are decompositions:
- 23 + 173219 = 173242
- 53 + 173189 = 173242
- 59 + 173183 = 173242
- 101 + 173141 = 173242
- 269 + 172973 = 173242
- 359 + 172883 = 173242
- 383 + 172859 = 173242
- 389 + 172853 = 173242
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 173,242 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 173242 first appears in π at position 674,006 of the decimal expansion (the 674,006ordinal-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.
