Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668900, here are decompositions:

  • 3 + 8668897 = 8668900
  • 11 + 8668889 = 8668900
  • 83 + 8668817 = 8668900
  • 101 + 8668799 = 8668900
  • 137 + 8668763 = 8668900
  • 179 + 8668721 = 8668900
  • 257 + 8668643 = 8668900
  • 263 + 8668637 = 8668900

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 8,668,900 and was likely granted around 2014.

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