Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 63880, here are decompositions:

  • 17 + 63863 = 63880
  • 23 + 63857 = 63880
  • 41 + 63839 = 63880
  • 71 + 63809 = 63880
  • 107 + 63773 = 63880
  • 137 + 63743 = 63880
  • 191 + 63689 = 63880
  • 233 + 63647 = 63880

Showing the first eight; more decompositions exist.
