Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 174742, here are decompositions:
- 5 + 174737 = 174742
- 83 + 174659 = 174742
- 89 + 174653 = 174742
- 173 + 174569 = 174742
- 251 + 174491 = 174742
- 311 + 174431 = 174742
- 353 + 174389 = 174742
- 431 + 174311 = 174742
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 174,742 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 174742 first appears in π at position 414,829 of the decimal expansion (the 414,829ordinal-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.
