Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12112, here are decompositions:

  • 3 + 12109 = 12112
  • 5 + 12107 = 12112
  • 11 + 12101 = 12112
  • 41 + 12071 = 12112
  • 71 + 12041 = 12112
  • 101 + 12011 = 12112
  • 131 + 11981 = 12112
  • 173 + 11939 = 12112

Showing the first eight; more decompositions exist.
