Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30732, here are decompositions:

  • 5 + 30727 = 30732
  • 19 + 30713 = 30732
  • 29 + 30703 = 30732
  • 43 + 30689 = 30732
  • 61 + 30671 = 30732
  • 71 + 30661 = 30732
  • 83 + 30649 = 30732
  • 89 + 30643 = 30732

Showing the first eight; more decompositions exist.
