Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672200, here are decompositions:

  • 23 + 8672177 = 8672200
  • 83 + 8672117 = 8672200
  • 101 + 8672099 = 8672200
  • 113 + 8672087 = 8672200
  • 137 + 8672063 = 8672200
  • 197 + 8672003 = 8672200
  • 233 + 8671967 = 8672200
  • 263 + 8671937 = 8672200

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 8,672,200 and was likely granted around 2014.

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