Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667810, here are decompositions:

  • 13 + 8667797 = 8667810
  • 17 + 8667793 = 8667810
  • 83 + 8667727 = 8667810
  • 89 + 8667721 = 8667810
  • 103 + 8667707 = 8667810
  • 113 + 8667697 = 8667810
  • 149 + 8667661 = 8667810
  • 157 + 8667653 = 8667810

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 8,667,810 and was likely granted around 2014.

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