Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 167580, here are decompositions:
- 37 + 167543 = 167580
- 43 + 167537 = 167580
- 59 + 167521 = 167580
- 89 + 167491 = 167580
- 97 + 167483 = 167580
- 109 + 167471 = 167580
- 131 + 167449 = 167580
- 137 + 167443 = 167580
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 167,580 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 167580 first appears in π at position 72,456 of the decimal expansion (the 72,456ordinal-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.
