Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670866, here are decompositions:

  • 3 + 8670863 = 8670866
  • 157 + 8670709 = 8670866
  • 163 + 8670703 = 8670866
  • 199 + 8670667 = 8670866
  • 229 + 8670637 = 8670866
  • 277 + 8670589 = 8670866
  • 283 + 8670583 = 8670866
  • 307 + 8670559 = 8670866

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 8,670,866 and was likely granted around 2014.

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