Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722884, here are decompositions:

  • 7 + 8722877 = 8722884
  • 43 + 8722841 = 8722884
  • 127 + 8722757 = 8722884
  • 173 + 8722711 = 8722884
  • 211 + 8722673 = 8722884
  • 223 + 8722661 = 8722884
  • 241 + 8722643 = 8722884
  • 263 + 8722621 = 8722884

Showing the first eight; more decompositions exist.
