Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12238, here are decompositions:

  • 11 + 12227 = 12238
  • 41 + 12197 = 12238
  • 89 + 12149 = 12238
  • 131 + 12107 = 12238
  • 137 + 12101 = 12238
  • 167 + 12071 = 12238
  • 197 + 12041 = 12238
  • 227 + 12011 = 12238

Showing the first eight; more decompositions exist.
