Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622084, here are decompositions:

  • 3 + 31622081 = 31622084
  • 37 + 31622047 = 31622084
  • 103 + 31621981 = 31622084
  • 127 + 31621957 = 31622084
  • 331 + 31621753 = 31622084
  • 433 + 31621651 = 31622084
  • 463 + 31621621 = 31622084
  • 523 + 31621561 = 31622084

Showing the first eight; more decompositions exist.
