Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2958, here are decompositions:

  • 5 + 2953 = 2958
  • 19 + 2939 = 2958
  • 31 + 2927 = 2958
  • 41 + 2917 = 2958
  • 61 + 2897 = 2958
  • 71 + 2887 = 2958
  • 79 + 2879 = 2958
  • 97 + 2861 = 2958

Showing the first eight; more decompositions exist.
