Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669842, here are decompositions:

  • 11 + 8669831 = 8669842
  • 173 + 8669669 = 8669842
  • 191 + 8669651 = 8669842
  • 353 + 8669489 = 8669842
  • 359 + 8669483 = 8669842
  • 431 + 8669411 = 8669842
  • 443 + 8669399 = 8669842
  • 449 + 8669393 = 8669842

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 8 669 842 and was likely granted around 2014.

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