Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 167240, here are decompositions:
- 19 + 167221 = 167240
- 43 + 167197 = 167240
- 67 + 167173 = 167240
- 127 + 167113 = 167240
- 163 + 167077 = 167240
- 193 + 167047 = 167240
- 223 + 167017 = 167240
- 331 + 166909 = 167240
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 167,240 and was likely granted around 1874.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
