Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 167142, here are decompositions:
- 23 + 167119 = 167142
- 29 + 167113 = 167142
- 43 + 167099 = 167142
- 61 + 167081 = 167142
- 71 + 167071 = 167142
- 103 + 167039 = 167142
- 109 + 167033 = 167142
- 163 + 166979 = 167142
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 167,142 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 167142 first appears in π at position 753,507 of the decimal expansion (the 753,507ordinal-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.
