Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12208, here are decompositions:

  • 5 + 12203 = 12208
  • 11 + 12197 = 12208
  • 47 + 12161 = 12208
  • 59 + 12149 = 12208
  • 89 + 12119 = 12208
  • 101 + 12107 = 12208
  • 107 + 12101 = 12208
  • 137 + 12071 = 12208

Showing the first eight; more decompositions exist.
