Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 970, here are decompositions:

  • 3 + 967 = 970
  • 17 + 953 = 970
  • 23 + 947 = 970
  • 29 + 941 = 970
  • 41 + 929 = 970
  • 59 + 911 = 970
  • 83 + 887 = 970
  • 89 + 881 = 970

Showing the first eight; more decompositions exist.
