Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671200, here are decompositions:

  • 7 + 8671193 = 8671200
  • 23 + 8671177 = 8671200
  • 53 + 8671147 = 8671200
  • 67 + 8671133 = 8671200
  • 73 + 8671127 = 8671200
  • 101 + 8671099 = 8671200
  • 103 + 8671097 = 8671200
  • 137 + 8671063 = 8671200

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 8,671,200 and was likely granted around 2014.

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