Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681138, here are decompositions:

  • 7 + 8681131 = 8681138
  • 61 + 8681077 = 8681138
  • 79 + 8681059 = 8681138
  • 199 + 8680939 = 8681138
  • 229 + 8680909 = 8681138
  • 337 + 8680801 = 8681138
  • 397 + 8680741 = 8681138
  • 421 + 8680717 = 8681138

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 8.681.138 and was likely granted around 2014.

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