Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 167540, here are decompositions:
- 3 + 167537 = 167540
- 19 + 167521 = 167540
- 97 + 167443 = 167540
- 103 + 167437 = 167540
- 127 + 167413 = 167540
- 199 + 167341 = 167540
- 211 + 167329 = 167540
- 223 + 167317 = 167540
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 167,540 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 167540 first appears in π at position 85,464 of the decimal expansion (the 85,464ordinal-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.
