Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670686, here are decompositions:

  • 7 + 8670679 = 8670686
  • 19 + 8670667 = 8670686
  • 67 + 8670619 = 8670686
  • 97 + 8670589 = 8670686
  • 103 + 8670583 = 8670686
  • 127 + 8670559 = 8670686
  • 163 + 8670523 = 8670686
  • 313 + 8670373 = 8670686

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 8,670,686 and was likely granted around 2014.

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