Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12150, here are decompositions:

  • 7 + 12143 = 12150
  • 31 + 12119 = 12150
  • 37 + 12113 = 12150
  • 41 + 12109 = 12150
  • 43 + 12107 = 12150
  • 53 + 12097 = 12150
  • 79 + 12071 = 12150
  • 101 + 12049 = 12150

Showing the first eight; more decompositions exist.
