Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 167904, here are decompositions:
- 5 + 167899 = 167904
- 13 + 167891 = 167904
- 17 + 167887 = 167904
- 31 + 167873 = 167904
- 41 + 167863 = 167904
- 43 + 167861 = 167904
- 103 + 167801 = 167904
- 127 + 167777 = 167904
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 167,904 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 167904 first appears in π at position 402,197 of the decimal expansion (the 402,197ordinal-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.
