Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 167900, here are decompositions:
- 13 + 167887 = 167900
- 37 + 167863 = 167900
- 223 + 167677 = 167900
- 277 + 167623 = 167900
- 307 + 167593 = 167900
- 379 + 167521 = 167900
- 409 + 167491 = 167900
- 457 + 167443 = 167900
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 167,900 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 167900 first appears in π at position 339,800 of the decimal expansion (the 339,800ordinal-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.
