Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65778, here are decompositions:

  • 17 + 65761 = 65778
  • 47 + 65731 = 65778
  • 59 + 65719 = 65778
  • 61 + 65717 = 65778
  • 71 + 65707 = 65778
  • 79 + 65699 = 65778
  • 101 + 65677 = 65778
  • 127 + 65651 = 65778

Showing the first eight; more decompositions exist.
