Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 167140, here are decompositions:
- 23 + 167117 = 167140
- 41 + 167099 = 167140
- 53 + 167087 = 167140
- 59 + 167081 = 167140
- 89 + 167051 = 167140
- 101 + 167039 = 167140
- 107 + 167033 = 167140
- 131 + 167009 = 167140
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 167,140 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 167140 first appears in π at position 53,104 of the decimal expansion (the 53,104ordinal-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.
