Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 168600, here are decompositions:

  • 41 + 168559 = 168600
  • 59 + 168541 = 168600
  • 67 + 168533 = 168600
  • 73 + 168527 = 168600
  • 101 + 168499 = 168600
  • 109 + 168491 = 168600
  • 137 + 168463 = 168600
  • 149 + 168451 = 168600

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 168,600 and was likely granted around 1874.

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