Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 29988, here are decompositions:

  • 5 + 29983 = 29988
  • 29 + 29959 = 29988
  • 41 + 29947 = 29988
  • 61 + 29927 = 29988
  • 67 + 29921 = 29988
  • 71 + 29917 = 29988
  • 107 + 29881 = 29988
  • 109 + 29879 = 29988

Showing the first eight; more decompositions exist.
