Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8682180, here are decompositions:

  • 37 + 8682143 = 8682180
  • 47 + 8682133 = 8682180
  • 53 + 8682127 = 8682180
  • 83 + 8682097 = 8682180
  • 113 + 8682067 = 8682180
  • 137 + 8682043 = 8682180
  • 139 + 8682041 = 8682180
  • 173 + 8682007 = 8682180

Showing the first eight; more decompositions exist.
