Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 167444, here are decompositions:
- 3 + 167441 = 167444
- 7 + 167437 = 167444
- 31 + 167413 = 167444
- 37 + 167407 = 167444
- 103 + 167341 = 167444
- 127 + 167317 = 167444
- 223 + 167221 = 167444
- 271 + 167173 = 167444
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 167,444 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 167444 first appears in π at position 261,849 of the decimal expansion (the 261,849ordinal-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.
