Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 167542, here are decompositions:
- 5 + 167537 = 167542
- 59 + 167483 = 167542
- 71 + 167471 = 167542
- 101 + 167441 = 167542
- 113 + 167429 = 167542
- 149 + 167393 = 167542
- 233 + 167309 = 167542
- 281 + 167261 = 167542
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 167,542 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 167542 first appears in π at position 659,525 of the decimal expansion (the 659,525ordinal-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.
