Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1152, here are decompositions:

  • 23 + 1129 = 1152
  • 29 + 1123 = 1152
  • 43 + 1109 = 1152
  • 59 + 1093 = 1152
  • 61 + 1091 = 1152
  • 83 + 1069 = 1152
  • 89 + 1063 = 1152
  • 101 + 1051 = 1152

Showing the first eight; more decompositions exist.
