Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 167644, here are decompositions:
- 3 + 167641 = 167644
- 11 + 167633 = 167644
- 17 + 167627 = 167644
- 23 + 167621 = 167644
- 47 + 167597 = 167644
- 101 + 167543 = 167644
- 107 + 167537 = 167644
- 173 + 167471 = 167644
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 167,644 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 167644 first appears in π at position 148,365 of the decimal expansion (the 148,365ordinal-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.
