Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 167400, here are decompositions:
- 7 + 167393 = 167400
- 19 + 167381 = 167400
- 59 + 167341 = 167400
- 61 + 167339 = 167400
- 71 + 167329 = 167400
- 83 + 167317 = 167400
- 89 + 167311 = 167400
- 131 + 167269 = 167400
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 167,400 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 167400 first appears in π at position 426,685 of the decimal expansion (the 426,685ordinal-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.
