Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9120, here are decompositions:

  • 11 + 9109 = 9120
  • 17 + 9103 = 9120
  • 29 + 9091 = 9120
  • 53 + 9067 = 9120
  • 61 + 9059 = 9120
  • 71 + 9049 = 9120
  • 79 + 9041 = 9120
  • 107 + 9013 = 9120

Showing the first eight; more decompositions exist.
