Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66928, here are decompositions:

  • 5 + 66923 = 66928
  • 107 + 66821 = 66928
  • 131 + 66797 = 66928
  • 137 + 66791 = 66928
  • 179 + 66749 = 66928
  • 227 + 66701 = 66928
  • 311 + 66617 = 66928
  • 359 + 66569 = 66928

Showing the first eight; more decompositions exist.
