Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 167860, here are decompositions:
- 59 + 167801 = 167860
- 83 + 167777 = 167860
- 89 + 167771 = 167860
- 101 + 167759 = 167860
- 113 + 167747 = 167860
- 131 + 167729 = 167860
- 149 + 167711 = 167860
- 197 + 167663 = 167860
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 167,860 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 167860 first appears in π at position 820,669 of the decimal expansion (the 820,669ordinal-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.
