Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1170, here are decompositions:

  • 7 + 1163 = 1170
  • 17 + 1153 = 1170
  • 19 + 1151 = 1170
  • 41 + 1129 = 1170
  • 47 + 1123 = 1170
  • 53 + 1117 = 1170
  • 61 + 1109 = 1170
  • 67 + 1103 = 1170

Showing the first eight; more decompositions exist.
