Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681042, here are decompositions:

  • 103 + 8680939 = 8681042
  • 229 + 8680813 = 8681042
  • 241 + 8680801 = 8681042
  • 373 + 8680669 = 8681042
  • 499 + 8680543 = 8681042
  • 541 + 8680501 = 8681042
  • 571 + 8680471 = 8681042
  • 673 + 8680369 = 8681042

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 8,681,042 and was likely granted around 2014.

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