Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1162, here are decompositions:

  • 11 + 1151 = 1162
  • 53 + 1109 = 1162
  • 59 + 1103 = 1162
  • 71 + 1091 = 1162
  • 101 + 1061 = 1162
  • 113 + 1049 = 1162
  • 131 + 1031 = 1162
  • 149 + 1013 = 1162

Showing the first eight; more decompositions exist.
