Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1166, here are decompositions:

  • 3 + 1163 = 1166
  • 13 + 1153 = 1166
  • 37 + 1129 = 1166
  • 43 + 1123 = 1166
  • 73 + 1093 = 1166
  • 79 + 1087 = 1166
  • 97 + 1069 = 1166
  • 103 + 1063 = 1166

Showing the first eight; more decompositions exist.
