Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8682120, here are decompositions:

  • 23 + 8682097 = 8682120
  • 53 + 8682067 = 8682120
  • 79 + 8682041 = 8682120
  • 113 + 8682007 = 8682120
  • 131 + 8681989 = 8682120
  • 151 + 8681969 = 8682120
  • 163 + 8681957 = 8682120
  • 179 + 8681941 = 8682120

Showing the first eight; more decompositions exist.
