Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690800, here are decompositions:

  • 3 + 8690797 = 8690800
  • 11 + 8690789 = 8690800
  • 17 + 8690783 = 8690800
  • 59 + 8690741 = 8690800
  • 137 + 8690663 = 8690800
  • 197 + 8690603 = 8690800
  • 233 + 8690567 = 8690800
  • 269 + 8690531 = 8690800

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 8,690,800 and was likely granted around 2014.

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