Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668420, here are decompositions:

  • 17 + 8668403 = 8668420
  • 41 + 8668379 = 8668420
  • 53 + 8668367 = 8668420
  • 71 + 8668349 = 8668420
  • 227 + 8668193 = 8668420
  • 263 + 8668157 = 8668420
  • 269 + 8668151 = 8668420
  • 347 + 8668073 = 8668420

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 8,668,420 and was likely granted around 2014.

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