Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 168918, here are decompositions:

  • 5 + 168913 = 168918
  • 17 + 168901 = 168918
  • 19 + 168899 = 168918
  • 31 + 168887 = 168918
  • 67 + 168851 = 168918
  • 137 + 168781 = 168918
  • 149 + 168769 = 168918
  • 157 + 168761 = 168918

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 168,918 and was likely granted around 1874.

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