Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722836, here are decompositions:

  • 7 + 8722829 = 8722836
  • 37 + 8722799 = 8722836
  • 47 + 8722789 = 8722836
  • 79 + 8722757 = 8722836
  • 97 + 8722739 = 8722836
  • 163 + 8722673 = 8722836
  • 193 + 8722643 = 8722836
  • 223 + 8722613 = 8722836

Showing the first eight; more decompositions exist.
