Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 964, here are decompositions:

  • 11 + 953 = 964
  • 17 + 947 = 964
  • 23 + 941 = 964
  • 53 + 911 = 964
  • 83 + 881 = 964
  • 101 + 863 = 964
  • 107 + 857 = 964
  • 137 + 827 = 964

Showing the first eight; more decompositions exist.
