Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2974, here are decompositions:

  • 3 + 2971 = 2974
  • 5 + 2969 = 2974
  • 11 + 2963 = 2974
  • 17 + 2957 = 2974
  • 47 + 2927 = 2974
  • 71 + 2903 = 2974
  • 113 + 2861 = 2974
  • 131 + 2843 = 2974

Showing the first eight; more decompositions exist.
