Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8682840, here are decompositions:

  • 83 + 8682757 = 8682840
  • 97 + 8682743 = 8682840
  • 113 + 8682727 = 8682840
  • 139 + 8682701 = 8682840
  • 149 + 8682691 = 8682840
  • 181 + 8682659 = 8682840
  • 251 + 8682589 = 8682840
  • 263 + 8682577 = 8682840

Showing the first eight; more decompositions exist.
