Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681140, here are decompositions:

  • 11 + 8681129 = 8681140
  • 23 + 8681117 = 8681140
  • 29 + 8681111 = 8681140
  • 131 + 8681009 = 8681140
  • 137 + 8681003 = 8681140
  • 233 + 8680907 = 8681140
  • 239 + 8680901 = 8681140
  • 269 + 8680871 = 8681140

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 8.681.140 and was likely granted around 2014.

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