Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680660, here are decompositions:

  • 29 + 8680631 = 8680660
  • 41 + 8680619 = 8680660
  • 47 + 8680613 = 8680660
  • 59 + 8680601 = 8680660
  • 101 + 8680559 = 8680660
  • 179 + 8680481 = 8680660
  • 251 + 8680409 = 8680660
  • 269 + 8680391 = 8680660

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 8,680,660 and was likely granted around 2014.

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