Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 168078, here are decompositions:

  • 7 + 168071 = 168078
  • 11 + 168067 = 168078
  • 41 + 168037 = 168078
  • 107 + 167971 = 168078
  • 167 + 167911 = 168078
  • 179 + 167899 = 168078
  • 191 + 167887 = 168078
  • 199 + 167879 = 168078

Showing the first eight; more decompositions exist.

Possible US patent number

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 168,078 and was likely granted around 1874.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
