Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38778, here are decompositions:

  • 11 + 38767 = 38778
  • 29 + 38749 = 38778
  • 31 + 38747 = 38778
  • 41 + 38737 = 38778
  • 67 + 38711 = 38778
  • 71 + 38707 = 38778
  • 79 + 38699 = 38778
  • 101 + 38677 = 38778

Showing the first eight; more decompositions exist.
