Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668558, here are decompositions:

  • 5 + 8668553 = 8668558
  • 11 + 8668547 = 8668558
  • 137 + 8668421 = 8668558
  • 179 + 8668379 = 8668558
  • 191 + 8668367 = 8668558
  • 257 + 8668301 = 8668558
  • 401 + 8668157 = 8668558
  • 491 + 8668067 = 8668558

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 8,668,558 and was likely granted around 2014.

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