Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1120, here are decompositions:

  • 3 + 1117 = 1120
  • 11 + 1109 = 1120
  • 17 + 1103 = 1120
  • 23 + 1097 = 1120
  • 29 + 1091 = 1120
  • 59 + 1061 = 1120
  • 71 + 1049 = 1120
  • 89 + 1031 = 1120

Showing the first eight; more decompositions exist.
