Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6820, here are decompositions:

  • 17 + 6803 = 6820
  • 29 + 6791 = 6820
  • 41 + 6779 = 6820
  • 59 + 6761 = 6820
  • 83 + 6737 = 6820
  • 101 + 6719 = 6820
  • 131 + 6689 = 6820
  • 167 + 6653 = 6820

Showing the first eight; more decompositions exist.
