Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66984, here are decompositions:

  • 7 + 66977 = 66984
  • 11 + 66973 = 66984
  • 37 + 66947 = 66984
  • 41 + 66943 = 66984
  • 53 + 66931 = 66984
  • 61 + 66923 = 66984
  • 101 + 66883 = 66984
  • 107 + 66877 = 66984

Showing the first eight; more decompositions exist.
