Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 167870, here are decompositions:
- 7 + 167863 = 167870
- 61 + 167809 = 167870
- 193 + 167677 = 167870
- 229 + 167641 = 167870
- 277 + 167593 = 167870
- 349 + 167521 = 167870
- 379 + 167491 = 167870
- 421 + 167449 = 167870
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 167,870 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 167870 first appears in π at position 15,764 of the decimal expansion (the 15,764ordinal-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.
