Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2834, here are decompositions:

  • 31 + 2803 = 2834
  • 37 + 2797 = 2834
  • 43 + 2791 = 2834
  • 67 + 2767 = 2834
  • 103 + 2731 = 2834
  • 127 + 2707 = 2834
  • 151 + 2683 = 2834
  • 157 + 2677 = 2834

Showing the first eight; more decompositions exist.
