Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681724, here are decompositions:

  • 17 + 8681707 = 8681724
  • 31 + 8681693 = 8681724
  • 61 + 8681663 = 8681724
  • 101 + 8681623 = 8681724
  • 137 + 8681587 = 8681724
  • 157 + 8681567 = 8681724
  • 211 + 8681513 = 8681724
  • 241 + 8681483 = 8681724

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 8,681,724 and was likely granted around 2014.

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