Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 167556, here are decompositions:
- 13 + 167543 = 167556
- 19 + 167537 = 167556
- 73 + 167483 = 167556
- 107 + 167449 = 167556
- 113 + 167443 = 167556
- 127 + 167429 = 167556
- 149 + 167407 = 167556
- 163 + 167393 = 167556
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 167,556 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 167556 first appears in π at position 743,216 of the decimal expansion (the 743,216ordinal-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.
