Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 167042, here are decompositions:
- 3 + 167039 = 167042
- 19 + 167023 = 167042
- 181 + 166861 = 167042
- 193 + 166849 = 167042
- 199 + 166843 = 167042
- 349 + 166693 = 167042
- 373 + 166669 = 167042
- 433 + 166609 = 167042
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 167,042 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 167042 first appears in π at position 76,488 of the decimal expansion (the 76,488ordinal-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.
