Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680666, here are decompositions:

  • 47 + 8680619 = 8680666
  • 53 + 8680613 = 8680666
  • 83 + 8680583 = 8680666
  • 107 + 8680559 = 8680666
  • 227 + 8680439 = 8680666
  • 257 + 8680409 = 8680666
  • 353 + 8680313 = 8680666
  • 359 + 8680307 = 8680666

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 8 680 666 and was likely granted around 2014.

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