Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 167840, here are decompositions:
- 31 + 167809 = 167840
- 61 + 167779 = 167840
- 157 + 167683 = 167840
- 163 + 167677 = 167840
- 199 + 167641 = 167840
- 229 + 167611 = 167840
- 349 + 167491 = 167840
- 397 + 167443 = 167840
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 167,840 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 167840 first appears in π at position 683,490 of the decimal expansion (the 683,490ordinal-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.
