Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668404, here are decompositions:

  • 23 + 8668381 = 8668404
  • 37 + 8668367 = 8668404
  • 47 + 8668357 = 8668404
  • 103 + 8668301 = 8668404
  • 131 + 8668273 = 8668404
  • 137 + 8668267 = 8668404
  • 197 + 8668207 = 8668404
  • 211 + 8668193 = 8668404

Showing the first eight; more decompositions exist.
