Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670240, here are decompositions:

  • 43 + 8670197 = 8670240
  • 83 + 8670157 = 8670240
  • 113 + 8670127 = 8670240
  • 151 + 8670089 = 8670240
  • 199 + 8670041 = 8670240
  • 211 + 8670029 = 8670240
  • 233 + 8670007 = 8670240
  • 251 + 8669989 = 8670240

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 8,670,240 and was likely granted around 2014.

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