Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669828, here are decompositions:

  • 7 + 8669821 = 8669828
  • 61 + 8669767 = 8669828
  • 127 + 8669701 = 8669828
  • 157 + 8669671 = 8669828
  • 199 + 8669629 = 8669828
  • 439 + 8669389 = 8669828
  • 487 + 8669341 = 8669828
  • 499 + 8669329 = 8669828

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 8,669,828 and was likely granted around 2014.

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