Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2926, here are decompositions:

  • 17 + 2909 = 2926
  • 23 + 2903 = 2926
  • 29 + 2897 = 2926
  • 47 + 2879 = 2926
  • 83 + 2843 = 2926
  • 89 + 2837 = 2926
  • 107 + 2819 = 2926
  • 137 + 2789 = 2926

Showing the first eight; more decompositions exist.
