Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681970, here are decompositions:

  • 13 + 8681957 = 8681970
  • 29 + 8681941 = 8681970
  • 47 + 8681923 = 8681970
  • 71 + 8681899 = 8681970
  • 113 + 8681857 = 8681970
  • 139 + 8681831 = 8681970
  • 149 + 8681821 = 8681970
  • 181 + 8681789 = 8681970

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 8,681,970 and was likely granted around 2014.

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