Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622188, here are decompositions:

  • 5 + 31622183 = 31622188
  • 41 + 31622147 = 31622188
  • 47 + 31622141 = 31622188
  • 107 + 31622081 = 31622188
  • 239 + 31621949 = 31622188
  • 449 + 31621739 = 31622188
  • 509 + 31621679 = 31622188
  • 557 + 31621631 = 31622188

Showing the first eight; more decompositions exist.
