Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536568, here are decompositions:

  • 17 + 31536551 = 31536568
  • 29 + 31536539 = 31536568
  • 47 + 31536521 = 31536568
  • 281 + 31536287 = 31536568
  • 467 + 31536101 = 31536568
  • 587 + 31535981 = 31536568
  • 659 + 31535909 = 31536568
  • 821 + 31535747 = 31536568

Showing the first eight; more decompositions exist.
