Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 167578, here are decompositions:
- 41 + 167537 = 167578
- 107 + 167471 = 167578
- 137 + 167441 = 167578
- 149 + 167429 = 167578
- 197 + 167381 = 167578
- 239 + 167339 = 167578
- 269 + 167309 = 167578
- 311 + 167267 = 167578
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 167,578 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 167578 first appears in π at position 230,976 of the decimal expansion (the 230,976ordinal-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.
