Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720584, here are decompositions:

  • 3 + 8720581 = 8720584
  • 53 + 8720531 = 8720584
  • 71 + 8720513 = 8720584
  • 101 + 8720483 = 8720584
  • 107 + 8720477 = 8720584
  • 113 + 8720471 = 8720584
  • 137 + 8720447 = 8720584
  • 167 + 8720417 = 8720584

Showing the first eight; more decompositions exist.
