Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672000, here are decompositions:

  • 13 + 8671987 = 8672000
  • 19 + 8671981 = 8672000
  • 163 + 8671837 = 8672000
  • 331 + 8671669 = 8672000
  • 367 + 8671633 = 8672000
  • 499 + 8671501 = 8672000
  • 607 + 8671393 = 8672000
  • 619 + 8671381 = 8672000

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 8,672,000 and was likely granted around 2014.

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