Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680988, here are decompositions:

  • 37 + 8680951 = 8680988
  • 67 + 8680921 = 8680988
  • 79 + 8680909 = 8680988
  • 271 + 8680717 = 8680988
  • 487 + 8680501 = 8680988
  • 571 + 8680417 = 8680988
  • 619 + 8680369 = 8680988
  • 661 + 8680327 = 8680988

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 8 680 988 and was likely granted around 2014.

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