Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 167668, here are decompositions:
- 5 + 167663 = 167668
- 41 + 167627 = 167668
- 47 + 167621 = 167668
- 71 + 167597 = 167668
- 131 + 167537 = 167668
- 197 + 167471 = 167668
- 227 + 167441 = 167668
- 239 + 167429 = 167668
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 167,668 and was likely granted around 1874.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
