Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 168812, here are decompositions:

  • 31 + 168781 = 168812
  • 43 + 168769 = 168812
  • 139 + 168673 = 168812
  • 181 + 168631 = 168812
  • 211 + 168601 = 168812
  • 271 + 168541 = 168812
  • 313 + 168499 = 168812
  • 331 + 168481 = 168812

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 168,812 and was likely granted around 1874.

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