Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667320, here are decompositions:

  • 7 + 8667313 = 8667320
  • 19 + 8667301 = 8667320
  • 31 + 8667289 = 8667320
  • 199 + 8667121 = 8667320
  • 241 + 8667079 = 8667320
  • 331 + 8666989 = 8667320
  • 367 + 8666953 = 8667320
  • 439 + 8666881 = 8667320

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 8,667,320 and was likely granted around 2014.

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