Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669000, here are decompositions:

  • 7 + 8668993 = 8669000
  • 103 + 8668897 = 8669000
  • 127 + 8668873 = 8669000
  • 163 + 8668837 = 8669000
  • 199 + 8668801 = 8669000
  • 313 + 8668687 = 8669000
  • 499 + 8668501 = 8669000
  • 541 + 8668459 = 8669000

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 8,669,000 and was likely granted around 2014.

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