Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13784, here are decompositions:

  • 3 + 13781 = 13784
  • 61 + 13723 = 13784
  • 73 + 13711 = 13784
  • 97 + 13687 = 13784
  • 103 + 13681 = 13784
  • 151 + 13633 = 13784
  • 157 + 13627 = 13784
  • 193 + 13591 = 13784

Showing the first eight; more decompositions exist.
