Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670400, here are decompositions:

  • 3 + 8670397 = 8670400
  • 29 + 8670371 = 8670400
  • 47 + 8670353 = 8670400
  • 293 + 8670107 = 8670400
  • 311 + 8670089 = 8670400
  • 359 + 8670041 = 8670400
  • 419 + 8669981 = 8670400
  • 461 + 8669939 = 8670400

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 8,670,400 and was likely granted around 2014.

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