Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722938, here are decompositions:

  • 47 + 8722891 = 8722938
  • 61 + 8722877 = 8722938
  • 79 + 8722859 = 8722938
  • 97 + 8722841 = 8722938
  • 109 + 8722829 = 8722938
  • 139 + 8722799 = 8722938
  • 149 + 8722789 = 8722938
  • 181 + 8722757 = 8722938

Showing the first eight; more decompositions exist.
