Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669160, here are decompositions:

  • 37 + 8669123 = 8669160
  • 43 + 8669117 = 8669160
  • 47 + 8669113 = 8669160
  • 53 + 8669107 = 8669160
  • 89 + 8669071 = 8669160
  • 167 + 8668993 = 8669160
  • 193 + 8668967 = 8669160
  • 263 + 8668897 = 8669160

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 8,669,160 and was likely granted around 2014.

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