Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668400, here are decompositions:

  • 19 + 8668381 = 8668400
  • 31 + 8668369 = 8668400
  • 43 + 8668357 = 8668400
  • 127 + 8668273 = 8668400
  • 193 + 8668207 = 8668400
  • 199 + 8668201 = 8668400
  • 337 + 8668063 = 8668400
  • 421 + 8667979 = 8668400

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 8,668,400 and was likely granted around 2014.

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