Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670020, here are decompositions:

  • 13 + 8670007 = 8670020
  • 31 + 8669989 = 8670020
  • 97 + 8669923 = 8670020
  • 109 + 8669911 = 8670020
  • 127 + 8669893 = 8670020
  • 199 + 8669821 = 8670020
  • 349 + 8669671 = 8670020
  • 397 + 8669623 = 8670020

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 8,670,020 and was likely granted around 2014.

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