Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 168264, here are decompositions:
- 11 + 168253 = 168264
- 17 + 168247 = 168264
- 37 + 168227 = 168264
- 53 + 168211 = 168264
- 67 + 168197 = 168264
- 71 + 168193 = 168264
- 113 + 168151 = 168264
- 137 + 168127 = 168264
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 168,264 and was likely granted around 1874.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
