Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 167784, here are decompositions:
- 5 + 167779 = 167784
- 7 + 167777 = 167784
- 13 + 167771 = 167784
- 37 + 167747 = 167784
- 73 + 167711 = 167784
- 101 + 167683 = 167784
- 107 + 167677 = 167784
- 151 + 167633 = 167784
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 167,784 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 167784 first appears in π at position 587,286 of the decimal expansion (the 587,286ordinal-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.
