Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 167512, here are decompositions:
- 29 + 167483 = 167512
- 41 + 167471 = 167512
- 71 + 167441 = 167512
- 83 + 167429 = 167512
- 89 + 167423 = 167512
- 131 + 167381 = 167512
- 173 + 167339 = 167512
- 251 + 167261 = 167512
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 167,512 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 167512 first appears in π at position 85,373 of the decimal expansion (the 85,373ordinal-suffix:rd 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.
