Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 167242, here are decompositions:
- 29 + 167213 = 167242
- 83 + 167159 = 167242
- 191 + 167051 = 167242
- 233 + 167009 = 167242
- 263 + 166979 = 167242
- 269 + 166973 = 167242
- 293 + 166949 = 167242
- 311 + 166931 = 167242
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 167,242 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 167242 first appears in π at position 712,299 of the decimal expansion (the 712,299ordinal-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.
