Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 26778, here are decompositions:

  • 19 + 26759 = 26778
  • 41 + 26737 = 26778
  • 47 + 26731 = 26778
  • 61 + 26717 = 26778
  • 67 + 26711 = 26778
  • 79 + 26699 = 26778
  • 97 + 26681 = 26778
  • 109 + 26669 = 26778

Showing the first eight; more decompositions exist.
