Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670800, here are decompositions:

  • 97 + 8670703 = 8670800
  • 163 + 8670637 = 8670800
  • 181 + 8670619 = 8670800
  • 211 + 8670589 = 8670800
  • 241 + 8670559 = 8670800
  • 277 + 8670523 = 8670800
  • 349 + 8670451 = 8670800
  • 367 + 8670433 = 8670800

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 8,670,800 and was likely granted around 2014.

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