Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66700, here are decompositions:

  • 3 + 66697 = 66700
  • 17 + 66683 = 66700
  • 47 + 66653 = 66700
  • 71 + 66629 = 66700
  • 83 + 66617 = 66700
  • 107 + 66593 = 66700
  • 113 + 66587 = 66700
  • 131 + 66569 = 66700

Showing the first eight; more decompositions exist.
