Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61824, here are decompositions:

  • 5 + 61819 = 61824
  • 11 + 61813 = 61824
  • 43 + 61781 = 61824
  • 67 + 61757 = 61824
  • 73 + 61751 = 61824
  • 101 + 61723 = 61824
  • 107 + 61717 = 61824
  • 137 + 61687 = 61824

Showing the first eight; more decompositions exist.
