Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 834, here are decompositions:

  • 5 + 829 = 834
  • 7 + 827 = 834
  • 11 + 823 = 834
  • 13 + 821 = 834
  • 23 + 811 = 834
  • 37 + 797 = 834
  • 47 + 787 = 834
  • 61 + 773 = 834

Showing the first eight; more decompositions exist.
