Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722912, here are decompositions:

  • 53 + 8722859 = 8722912
  • 71 + 8722841 = 8722912
  • 83 + 8722829 = 8722912
  • 113 + 8722799 = 8722912
  • 173 + 8722739 = 8722912
  • 239 + 8722673 = 8722912
  • 251 + 8722661 = 8722912
  • 269 + 8722643 = 8722912

Showing the first eight; more decompositions exist.
