Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627706, here are decompositions:

  • 67 + 31627639 = 31627706
  • 79 + 31627627 = 31627706
  • 139 + 31627567 = 31627706
  • 163 + 31627543 = 31627706
  • 223 + 31627483 = 31627706
  • 349 + 31627357 = 31627706
  • 373 + 31627333 = 31627706
  • 457 + 31627249 = 31627706

Showing the first eight; more decompositions exist.
