Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31570706, here are decompositions:

  • 103 + 31570603 = 31570706
  • 199 + 31570507 = 31570706
  • 457 + 31570249 = 31570706
  • 487 + 31570219 = 31570706
  • 547 + 31570159 = 31570706
  • 619 + 31570087 = 31570706
  • 823 + 31569883 = 31570706
  • 877 + 31569829 = 31570706

Showing the first eight; more decompositions exist.
