Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66742, here are decompositions:

  • 3 + 66739 = 66742
  • 29 + 66713 = 66742
  • 41 + 66701 = 66742
  • 59 + 66683 = 66742
  • 89 + 66653 = 66742
  • 113 + 66629 = 66742
  • 149 + 66593 = 66742
  • 173 + 66569 = 66742

Showing the first eight; more decompositions exist.
