Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668426, here are decompositions:

  • 3 + 8668423 = 8668426
  • 5 + 8668421 = 8668426
  • 23 + 8668403 = 8668426
  • 47 + 8668379 = 8668426
  • 59 + 8668367 = 8668426
  • 233 + 8668193 = 8668426
  • 269 + 8668157 = 8668426
  • 293 + 8668133 = 8668426

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 8,668,426 and was likely granted around 2014.

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