Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718800, here are decompositions:

  • 3 + 8718797 = 8718800
  • 7 + 8718793 = 8718800
  • 43 + 8718757 = 8718800
  • 67 + 8718733 = 8718800
  • 73 + 8718727 = 8718800
  • 127 + 8718673 = 8718800
  • 151 + 8718649 = 8718800
  • 199 + 8718601 = 8718800

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 8,718,800 and was likely granted around 2014.

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