Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678800, here are decompositions:

  • 17 + 8678783 = 8678800
  • 23 + 8678777 = 8678800
  • 41 + 8678759 = 8678800
  • 47 + 8678753 = 8678800
  • 59 + 8678741 = 8678800
  • 101 + 8678699 = 8678800
  • 107 + 8678693 = 8678800
  • 131 + 8678669 = 8678800

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 8,678,800 and was likely granted around 2014.

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