Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71784, here are decompositions:

  • 7 + 71777 = 71784
  • 23 + 71761 = 71784
  • 43 + 71741 = 71784
  • 71 + 71713 = 71784
  • 73 + 71711 = 71784
  • 113 + 71671 = 71784
  • 137 + 71647 = 71784
  • 151 + 71633 = 71784

Showing the first eight; more decompositions exist.
