Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1140, here are decompositions:

  • 11 + 1129 = 1140
  • 17 + 1123 = 1140
  • 23 + 1117 = 1140
  • 31 + 1109 = 1140
  • 37 + 1103 = 1140
  • 43 + 1097 = 1140
  • 47 + 1093 = 1140
  • 53 + 1087 = 1140

Showing the first eight; more decompositions exist.
