Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 167280, here are decompositions:
- 11 + 167269 = 167280
- 13 + 167267 = 167280
- 19 + 167261 = 167280
- 31 + 167249 = 167280
- 59 + 167221 = 167280
- 67 + 167213 = 167280
- 83 + 167197 = 167280
- 89 + 167191 = 167280
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 167,280 and was likely granted around 1874.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
