Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672800, here are decompositions:

  • 11 + 8672789 = 8672800
  • 113 + 8672687 = 8672800
  • 179 + 8672621 = 8672800
  • 239 + 8672561 = 8672800
  • 281 + 8672519 = 8672800
  • 317 + 8672483 = 8672800
  • 359 + 8672441 = 8672800
  • 419 + 8672381 = 8672800

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 8,672,800 and was likely granted around 2014.

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