Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27808, here are decompositions:

  • 5 + 27803 = 27808
  • 17 + 27791 = 27808
  • 29 + 27779 = 27808
  • 41 + 27767 = 27808
  • 59 + 27749 = 27808
  • 71 + 27737 = 27808
  • 107 + 27701 = 27808
  • 191 + 27617 = 27808

Showing the first eight; more decompositions exist.
