Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720574, here are decompositions:

  • 17 + 8720557 = 8720574
  • 41 + 8720533 = 8720574
  • 43 + 8720531 = 8720574
  • 61 + 8720513 = 8720574
  • 97 + 8720477 = 8720574
  • 103 + 8720471 = 8720574
  • 127 + 8720447 = 8720574
  • 157 + 8720417 = 8720574

Showing the first eight; more decompositions exist.
