Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700800, here are decompositions:

  • 7 + 8700793 = 8700800
  • 79 + 8700721 = 8700800
  • 103 + 8700697 = 8700800
  • 151 + 8700649 = 8700800
  • 211 + 8700589 = 8700800
  • 271 + 8700529 = 8700800
  • 379 + 8700421 = 8700800
  • 439 + 8700361 = 8700800

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 8,700,800 and was likely granted around 2014.

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