Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668920, here are decompositions:

  • 19 + 8668901 = 8668920
  • 23 + 8668897 = 8668920
  • 31 + 8668889 = 8668920
  • 47 + 8668873 = 8668920
  • 83 + 8668837 = 8668920
  • 89 + 8668831 = 8668920
  • 103 + 8668817 = 8668920
  • 107 + 8668813 = 8668920

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 8.668.920 and was likely granted around 2014.

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