Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667790, here are decompositions:

  • 83 + 8667707 = 8667790
  • 101 + 8667689 = 8667790
  • 113 + 8667677 = 8667790
  • 137 + 8667653 = 8667790
  • 149 + 8667641 = 8667790
  • 179 + 8667611 = 8667790
  • 227 + 8667563 = 8667790
  • 251 + 8667539 = 8667790

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 8,667,790 and was likely granted around 2014.

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