Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1160, here are decompositions:

  • 7 + 1153 = 1160
  • 31 + 1129 = 1160
  • 37 + 1123 = 1160
  • 43 + 1117 = 1160
  • 67 + 1093 = 1160
  • 73 + 1087 = 1160
  • 97 + 1063 = 1160
  • 109 + 1051 = 1160

Showing the first eight; more decompositions exist.
