Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 167878, here are decompositions:
- 5 + 167873 = 167878
- 17 + 167861 = 167878
- 101 + 167777 = 167878
- 107 + 167771 = 167878
- 131 + 167747 = 167878
- 149 + 167729 = 167878
- 167 + 167711 = 167878
- 251 + 167627 = 167878
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 167,878 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 167878 first appears in π at position 531,528 of the decimal expansion (the 531,528ordinal-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.
