Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8682216, here are decompositions:

  • 5 + 8682211 = 8682216
  • 7 + 8682209 = 8682216
  • 13 + 8682203 = 8682216
  • 17 + 8682199 = 8682216
  • 73 + 8682143 = 8682216
  • 83 + 8682133 = 8682216
  • 89 + 8682127 = 8682216
  • 149 + 8682067 = 8682216

Showing the first eight; more decompositions exist.
