Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6778, here are decompositions:

  • 17 + 6761 = 6778
  • 41 + 6737 = 6778
  • 59 + 6719 = 6778
  • 89 + 6689 = 6778
  • 179 + 6599 = 6778
  • 197 + 6581 = 6778
  • 227 + 6551 = 6778
  • 257 + 6521 = 6778

Showing the first eight; more decompositions exist.
