Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 167520, here are decompositions:
- 29 + 167491 = 167520
- 37 + 167483 = 167520
- 71 + 167449 = 167520
- 79 + 167441 = 167520
- 83 + 167437 = 167520
- 97 + 167423 = 167520
- 107 + 167413 = 167520
- 113 + 167407 = 167520
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 167,520 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 167520 first appears in π at position 170,455 of the decimal expansion (the 170,455ordinal-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.
