Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 168664, here are decompositions:

  • 47 + 168617 = 168664
  • 131 + 168533 = 168664
  • 137 + 168527 = 168664
  • 173 + 168491 = 168664
  • 311 + 168353 = 168664
  • 317 + 168347 = 168664
  • 383 + 168281 = 168664
  • 401 + 168263 = 168664

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 168,664 and was likely granted around 1874.

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