Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 167572, here are decompositions:
- 29 + 167543 = 167572
- 89 + 167483 = 167572
- 101 + 167471 = 167572
- 131 + 167441 = 167572
- 149 + 167423 = 167572
- 179 + 167393 = 167572
- 191 + 167381 = 167572
- 233 + 167339 = 167572
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 167,572 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 167572 first appears in π at position 791,930 of the decimal expansion (the 791,930ordinal-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.
