Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 968, here are decompositions:

  • 31 + 937 = 968
  • 61 + 907 = 968
  • 109 + 859 = 968
  • 139 + 829 = 968
  • 157 + 811 = 968
  • 181 + 787 = 968
  • 199 + 769 = 968
  • 211 + 757 = 968

Showing the first eight; more decompositions exist.
