Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671040, here are decompositions:

  • 31 + 8671009 = 8671040
  • 43 + 8670997 = 8671040
  • 97 + 8670943 = 8671040
  • 229 + 8670811 = 8671040
  • 331 + 8670709 = 8671040
  • 337 + 8670703 = 8671040
  • 373 + 8670667 = 8671040
  • 421 + 8670619 = 8671040

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 8,671,040 and was likely granted around 2014.

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