Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666942, here are decompositions:

  • 3 + 8666939 = 8666942
  • 61 + 8666881 = 8666942
  • 79 + 8666863 = 8666942
  • 103 + 8666839 = 8666942
  • 409 + 8666533 = 8666942
  • 463 + 8666479 = 8666942
  • 499 + 8666443 = 8666942
  • 523 + 8666419 = 8666942

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 8,666,942 and was likely granted around 2014.

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