Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 163742, here are decompositions:
- 13 + 163729 = 163742
- 109 + 163633 = 163742
- 181 + 163561 = 163742
- 199 + 163543 = 163742
- 331 + 163411 = 163742
- 349 + 163393 = 163742
- 379 + 163363 = 163742
- 421 + 163321 = 163742
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 163,742 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 163742 first appears in π at position 412,105 of the decimal expansion (the 412,105ordinal-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.
