Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 167942, here are decompositions:
- 31 + 167911 = 167942
- 43 + 167899 = 167942
- 79 + 167863 = 167942
- 163 + 167779 = 167942
- 331 + 167611 = 167942
- 349 + 167593 = 167942
- 421 + 167521 = 167942
- 499 + 167443 = 167942
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 167,942 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 167942 first appears in π at position 242,489 of the decimal expansion (the 242,489ordinal-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.
