Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670850, here are decompositions:

  • 59 + 8670791 = 8670850
  • 107 + 8670743 = 8670850
  • 137 + 8670713 = 8670850
  • 197 + 8670653 = 8670850
  • 239 + 8670611 = 8670850
  • 317 + 8670533 = 8670850
  • 347 + 8670503 = 8670850
  • 359 + 8670491 = 8670850

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 8,670,850 and was likely granted around 2014.

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