Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1150, here are decompositions:

  • 41 + 1109 = 1150
  • 47 + 1103 = 1150
  • 53 + 1097 = 1150
  • 59 + 1091 = 1150
  • 89 + 1061 = 1150
  • 101 + 1049 = 1150
  • 131 + 1019 = 1150
  • 137 + 1013 = 1150

Showing the first eight; more decompositions exist.
