Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719400, here are decompositions:

  • 73 + 8719327 = 8719400
  • 97 + 8719303 = 8719400
  • 127 + 8719273 = 8719400
  • 139 + 8719261 = 8719400
  • 181 + 8719219 = 8719400
  • 223 + 8719177 = 8719400
  • 241 + 8719159 = 8719400
  • 379 + 8719021 = 8719400

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 8,719,400 and was likely granted around 2014.

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