Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66726, here are decompositions:

  • 5 + 66721 = 66726
  • 13 + 66713 = 66726
  • 29 + 66697 = 66726
  • 43 + 66683 = 66726
  • 73 + 66653 = 66726
  • 83 + 66643 = 66726
  • 97 + 66629 = 66726
  • 109 + 66617 = 66726

Showing the first eight; more decompositions exist.
