Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1190, here are decompositions:

  • 3 + 1187 = 1190
  • 19 + 1171 = 1190
  • 37 + 1153 = 1190
  • 61 + 1129 = 1190
  • 67 + 1123 = 1190
  • 73 + 1117 = 1190
  • 97 + 1093 = 1190
  • 103 + 1087 = 1190

Showing the first eight; more decompositions exist.
